	abstract = {A simple NMR method is presented for the identification and assignment of phosphorylated serine and threonine residues in C-13- or C-13/N-15-labeled proteins. By exploiting modest (similar to 5 Hz) 2- and 3-bond C-13-P-31 scalar couplings, the aliphatic H-1-C-13 signals from phosphoserines and phosphothreonines can be detected selectively in a P-31 spin-echo difference constant time H-1-C-13 HSQC spectrum. Inclusion of the same P-31 spin-echo element within the C-13 frequency editing period of an intraHNCA or HN(CO)CA experiment allows identification of the amide H-1(N) and N-15 signals of residues (i) for which C-13(alpha)(i) or C-13(alpha)(i - 1), respectively, are coupled to a phosphate. Furthermore, P-31 resonance assignments can be obtained by applying selective low power cw P-31 decoupling during the spin-echo period. The approach is demonstrated using a PNT domain containing fragment of the transcription factor Ets-1, phosphorylated in vitro at Thr38 and Ser41 with the MAP kinase ERK2.},

	abstract = {Ion motion with auxiliary dipole excitation and collisional damping in a linear radiofrequency quadrupole ion trap incorporating small amounts of even higher order multipoles is studied analytically. The ion motion is modeled in a pseudopotential that is mostly quadratic with small amounts of higher spatial harmonics. Ion motion along x and y axes is characterized by two uncoupled forced and damped anharmonic oscillator equations. A multiple time scales method is used to solve the equations of motion of ions with a first order perturbation Correction. Analytical relations between the oscillation amplitudes at steady state (the stationary amplitudes) and excitation frequency are calculated. The frequency response Curves show that in some cases bistable behavior might be obtained, i.e., there are two stable stationary amplitudes for a given excitation frequency.

In a linear ion trap, ions are confined radially by a two-dimensional (2D) radio frequency (RF) field, and axially by stopping potentials applied to end electrodes. This review focuses on linear ion trap instrumentation. Potentials and ion motion in linear multipole fields and methods of ion trapping, cooling, excitation, and isolation are described. This is followed by a description of various mass discrimination effects that have been reported with linear ion traps. Linear ion traps combined in various ways with three-dimensional (3D) traps, time-of-flight (TOF) mass analyzers, and Fourier transform ion cyclotron resonance mass spectrometers are then given. Linear ion traps can be used as stand alone mass analyzers, and their use for mass analysis by Fourier transforming image currents, by mass selective radial ejection, and by mass selective axial ejection are reviewed.

In addition, polarization fractions for the diamagnetic and Mu environments have been determined at different pressures, thereby complementing earlier data, and demonstrating that the RF-muSR technique provides polarization fractions in good accord with those obtained using conventional transverse-field muon spin resonance measurements.},

Diffusion coefficients were measured in unaligned samples in all of these phases. They were also obtained in the hexagonal and lamellar phases in oriented monodomain samples that were aligned by slow cooling from the micellar phase in an 11.7 T magnet. Measured water and soap diffusion coefficients in the NMR-isotropic cubic and (high-water-content) micellar phases as well as diffusion anisotropy measurements in the magnetically aligned hexagonal phase were quantitatively consistent with the constituent structures of these phases being identical surfactant cylinders, with only the fraction of surface-associated water varying with the water-soap molar ratio. The values of the water and soap diffusion coefficients in the oriented lamellar phase suggest an increase in defects and obstructions to soap diffusion as a function of increasing water content, while those in the low-water-content micellar phase rule out the presence of inverse micelles.},

	abstract = {The mechanism of formation of muonium atoms from positive muons was studied here through measurements of the yield of diamagnetic muon states in dipolar aprotic solvents and for scavenger solutions in hexane and methanol. The results are compared with published data on common solvents covering a full range of the physicochemical properties of liquids that affect an ionic formation mechanism, namely their static dielectric constants, electron mobilities, and radiolysis yields of electrons. It is concluded that muonium is not formed by a thermal charge-neutralization reaction in these chemically-active media, though that mechanism does contribute to muonium formation in inert media like liquefied noble gases. It is clear that muonium materializes on a much shorter timescale than the recently proposed "delayed" mechanism (microseconds) and the earlier "spur" model (nanoseconds). In contrast, the data referring to all these liquids are consistent with the intra-track "hot" model. This is the only Mu-formation model proposed so far in which the immediate precursors of Mu (Mu((hot))) are neither scavengable nor ionic.},

The first, {\textquoteright}stretching{\textquoteright} the quadrupole by moving two rods out from the axis, produces a combination of higher order fields with similar magnitudes in which the octopole field is not necessarily the greatest. The quadrupole field strength is changed significantly and a large potential appears on the axis. The second method uses rod pairs of different diameters. It adds octopole components of up to several percent while all other higher order fields remain small. An axis potential is also added, but it is only a few percent of the radio-frequency (RF) voltage and approximately equal to the strength of the octopole field. The axis potential can be removed by moving the larger rod pair out from the axis or applying unbalanced RIF to the electrodes. Copyright (C) 2003 John Wiley Sons, Ltd.},

	abstract = {Laser excitation spectra of yttrium monohydroxide, YOH, have been recorded in the 500-625 nm wavelength region. Rotational analysis of bands of YOH and YOD has shown that the ground state is (X) over tilde(1)Sigma(+), with the structure r(0)(Y-O) = 1.948(6) Angstrom, r(0)(O-H) = 0.920(6) Angstrom; the bending frequency (nu(2), pi) is 313.73 cm(-1) (237.43 cm(-1) in YOD) and the Y-O stretching frequency (nu(3), sigma(+)) is 673.83 cm(-1) (655.34 cm(-1)). Two excited electronic states have been identified; they are assigned as (B) over tilde(1)Pi (16 449 cm(-1)) and (C) over bar(1)Sigma(+) (18 509 cm(-1)). Unusually strong vibronic coupling through the bending vibration occurs between these two states, which causes their vibrational structures to be highly irregular; assignments have only been possible following extensive wavelength-resolved fluorescence experiments. The vibronic coupling raises the bending frequency of the (C) over tilde(1)Sigma(+) state to 457 cm(-1) and reduces that of the lower Born-Oppenheimer component of the (B) over tilde(1)Pi state (which has A{\textquoteright} symmetry in the C, point group) to the extent that the molecule becomes nonlinear, with a potential barrier at the linear configuration of about 120 cm(-1). The presence of the potential barrier is clearly demonstrated by the level structure of YOD, where the Sigma(+) vibronic component of the 010 vibrational level (linear molecule notation) lies 1.4 cm(-1) below the 000 level. The upper Born-Oppenheimer component, which has A " symmetry, is unaffected; its bending frequency is similar to that of the ground state. Perturbations occur in both the (B) over tilde(1)Pi and (C) over tilde(1)Sigma(+) states; some of these represent local interactions between the two of them, but others are caused by higher vibrational levels of lower-lying "dark" electronic states. Over 40 ground state vibrational levels have been identified for both YOH and YOD from the wavelength-resolved fluorescence spectra. (C) 1999 Academic Press.},

The instrument consists of an electrospray ionization source and two radio frequency (RF) only quadrupoles operating at a pressure of 7 mTorr N-2 which are coupled orthogonally to a linear TOFMS. Ions are trapped in an RF-only quadrupole through the application of timed stopping potentials on the entrance and exit apertures. Through the coupling of an auxiliary waveform generator on one pair of the ion trap rods a small dipolar excitation voltage is superimposed on the quadrupolar electric field. This voltage is used for precursor isolation via broadband excitation and collision induced dissociation through mass selective resonant excitation. Instrumental performance and choice of operating parameters are demonstrated by recording fragment spectra for +3 ions of renin substrate and fl ions of reserpine. TOFMS mass resolution (m/Delta m)(FWHM) is as high as 740 at m/z = 609. Fragmentation efficiency is greater than 50\% and excitation mass resolution is 60-75. (C) 1998 John Wiley \& Sons, Ltd.},

At 25.0 degrees C the protonation constants of Me(3)tren are not significantly different from those of tren and Me(6)tren, and the stability constant for the Cu(II) complex is of the same order of magnitude as that for the [Cu(tren)(H2O)](2+) complex ion; The pK(a) for deprotonation of the coordinated water molecule of [Cu(Me(3)tren)(H2O)](2+) is intermediate between the values for the complexes containing the unsubstituted and the fully substituted tren ligand. Substitution (pyridine for water) kinetics measurements employing stopped-flow and temperature-jump methods revealed different patterns of reactivity: pyridine replaces water in [Cu(Me(3)tren)(H2O)](2+) with a second-order rate constant of (4.4 +/- 0.8) x 10(2) M-1 s(-1) at 25.0 degrees C, whereas the corresponding process for [Cu(Me(6)tren)(H2O)](2+) is relatively complex and is discussed in more detail. Substitution in the former complex ion is characterized in the forward and reverse directions, by Delta H-double dagger = 60 +/- 8 and 51.9 +/- 0.9 kJ mol(-1), Delta S-double dagger = 5 +/- 27 and -23 +/- 3 J mol(-1) K-1, and Delta V-double dagger = -8.7 +/- 4.6 and -6.2 +/- 1.1 cm(3) mol(-1), respectively, It is concluded that this reaction follows an I-a mechanism, similar to that reported for the comparable reaction of [Cu(tren)(H2O)](2+). An X-ray structural determination on a crystal of [Cu-2(Me(3)tren)(2)(CN)] (ClO4)(3) . 2CH(3)CN demonstrated trigonal bipyramidal geometry about each copper(II) center. As has been found in comparable complexes of tren and Me(6)tren, the axial nitrogen to copper bond is shorter than the equatorial nitrogen-copper bonds, and the angle made by N(axial)-Cu-N(equatorial) is less than 90 degrees (84.6-85.4 degrees), signifying that each copper ion lies below the plane of the equatorial nitrogen atoms.},

The interpretation of the results for these small molecules, which are quite different than those obtained in larger molecule systems (e.g., Mu-ethyl and Mu-t-butyl radicals), are made with the phenomenological model for Mu-radical spin relaxation previously proposed. Proper fitting procedures are important in these cases and are discussed in the present paper.},

	abstract = {Muon spin rotation (mu SR) and avoided level crossing resonance (ALCR) have been used to determine the hyperfine coupling constants (hfcs) of the muonium-substituted cyclohexadienyl radicals C(6)H(6)Mu, C(6)D(6)Mu and C(6)F(6)Mu in the gas phase, at pressures similar to 1 and 15 atm and temperatures in the range 40-80 degrees C. Equivalent studies of polyatomic free radicals in gases, by electron spin resonance (ESR) spectroscopy, are generally not possible in this pressure range. The present gas phase results support the findings of earlier studies of cyclohexadienyl radicals in the condensed phase, by both mu SR and ESR. Minor but not insignificant (similar to 1\%) effects on the hfcs are observed, which can be qualitatively understood for such nonpolar media in terms of their differing polarizabilities. This is the first time that comparisons of this nature have been possible between different phases at the same temperatures. These mu SR/ALCR gas-phase results provide a valuable benchmark for computational studies on radicals, free from possible effects of solvent or matrix environments.},

	abstract = {A theoretical study of the muon spin relaxation of the gaseous muonated ethyl radical C(2)H(4)Mu is expanded in this paper to include both longitudinal and transverse signals. This study is based upon an operator expansion of the spin-density operator for the radical with its time dependence described by the linearized quantum Boltzmann equation. Relaxation is due to collisions which reorient the radical{\textquoteright}s rotational angular momentum while effects on the muon{\textquoteright}s spin are due to couplings between the muon{\textquoteright}s spin, the radical{\textquoteright}s free-electron spin, and the radical{\textquoteright}s rotational angular momentum. The coefficients of the radical{\textquoteright}s spin Hamiltonian and the collisional lifetimes (cross sections) are used as fitting parameters to describe the transverse signals. A fit to the transverse data by itself and a global fit to both the transverse and longitudinal data are obtained with good accuracy.},

	abstract = {The laser induced fluorescence spectrum of jet-cooled CoC near 750 nm has been measured at high resolution following the reaction of laser-ablated cobalt atoms with methane. The X(2) Sigma(+) ground state of CoC is an unusually good example of Hund{\textquoteright}s case (b(beta S)) coupling. Since Co has a nuclear spin I=7/2, each rotational level is split by the Fermi contact interaction into G=3 and G=4 components, where G=I+S; the splitting for N=0 is more than 0.5 cm(-1). The X(2) Sigma(+) state begins to uncouple toward case (b(beta J)) with increasing rotation. Transitions to various (II)-I-2 excited states occur in the region 13 000-14 500 cm(-1); the most prominent of these (for which high resolution spectra have been recorded) lie at 13 079 cm(-1) ((II3/2)-I-2) and 13 343 cm(-1) ((II1/2)-I-2). The (b(beta S)) coupling in the ground state produces some unexpected hyperfine intensity patterns, which have been studied in detail. A very low-lying (2) Delta(i) state, whose Omega=5/2 and Omega=3/2 components lie at 221 and 1173 cm(-1), has been identified. Laser excitation of the (II3/2)-I-2-(2) Delta(5/2) transition has been observed by monitoring the strong (II3/2)-I-2-X(2) Sigma(+) emission, which has allowed the (2) Delta(5/2) state to be characterized at high resolution. A total of 879 rotational-hyperfine transitions between the various (II1/2)-I-2, (II3/2)-I-2, (2) Delta(5/2), and (2) Sigma(+) states have been assigned and fitted. Matrix elements for a (2) Sigma(+) state in case (bps) coupling are listed. (C) 1995 American Institute of Physics.},

	abstract = {The VN molecule has been produced in a molecular beam apparatus using a laser vaporization source and its D3PI-X3DELTA (0,0) band has been studied by laser-induced fluorescence at low (approximately 0.1 cm-1) and sub-Doppler resolution (approximately 0.004 cm-1). Lifetimes of single rotational levels of the D3PI0 component have been measured and interpreted. Rotational, fine, and hyperfine structures in six of the nine subbands possible for a 3PI <{\textendash} 3DELTA transition have been recorded. Both states exhibit a rapid transition from case (a) {\textendash}> case (b) coupling cases, manifested by reversals in the Lande patterns of the hyperfine structure. The data have been reduced to a set of 35 molecular constants using a modified case (a(beta)) effective Hamiltonian in which two additional magnetic hyperfine parameters are required for each state. The distortions in the hyperfine structure are due almost entirely to second-order spin-orbit interaction between states arising from the same configuration. Analysis of the derived parameters indicates that the X3DELTA state is well represented by the single electron configuration ... 8sigma2 3pi4 9sigma1 1delta1, in which the 9sigma molecular orbital (MO) is a V 4s-4p hybrid (88\% V 4s) and the 1delta MO is-a pure V 3d orbital; the dominant configuration for the D3PI state is ... 8sigma2 3pi4 1delta1 4pi1, in which the 4pi MO is an antibonding orbital composed of at most 82\% V 3dpi. The isoconfigurational a 1DELTA and e 1PI states are calculated to lie 3390 and 2200 cm-1 above their respective high spin companions. The lambda doubling in the D3PI0 component has been interpreted in terms of spin-orbit interactions with the B3SIGMA- and d1SIGMA+ states, both states arising from the ... 8sigma2 3pi4 1delta2 configuration; the d1SIGMA+ state is known [Simard, Masoni, and Hackett, J. Mol. Spectrosc. 136, 44 (1989)] to lie 102 cm-1 above D3PI0, while the B3SIGMA- state probably lies about 8000 cm-1 below.},

	abstract = {The study of the reaction dynamics of muonium (Mu), an ultralight isotope of hydrogen ((m)Mu/(m)H almost-equal-to 1/9), provides a sensitive measure of mass effects in chemical reactions. The remarkable mass difference between Mu and the other hydrogen isotopes produces large kinetic isotope effects, providing a rigorous test of calculated potential energy surfaces (PES) and reaction rate theories. The low Mu mass also necessitates careful consideration of quantum effects, i.e. tunneling in the reaction coordinate. A review of recent results in gas phase Mu chemistry is presented, including comparison with relevant H chemistry and calculated PESs, where available. The magnitude and direction of the kinetic isotope effect is shown to be a sensitive function of the PES, particularly the height and position of the saddle point.},
