	abstract = {Pure rotational spectra have been measured for all the major isotopomers of the lanthanum monohalides, LaF, LaCl, LaBr, and LaI, in their ground and (except for (LaBr)-Br-81) excited vibrational states. The spectra were observed with a cavity pulsed jet Fourier transform microwave spectrometer in the frequency range 5-24 GHz. The molecules were prepared by laser ablation of La metal and allowing the resulting plasma to react with SF6, Cl-2, Br-2, or CH3I precursor in an Ar carrier gas of the pulsed jet. For LaBr this is the first reported spectrum of any kind. Rotational constants, centrifugal distortion constants, nuclear quadrupole coupling constants, and nuclear spin-rotation constants have been determined for all the molecules. Accurate equilibrium (r(e)) internuclear distances have given an indication of where the Born-Oppenheimer approximation is beginning to fail. From the centrifugal distortion constants and vibration-rotation (alpha(e)) constants good estimates of the harmonic vibration frequencies and bond dissociation energies have been obtained. The halogen nuclear quadrupole coupling constants indicate the molecules to be highly ionic. (C) 2003 Elsevier Science (USA). All rights reserved.},

	abstract = {The pure rotational spectra of (ScBr)-Br-7 9 and (ScBr)-Br-8 1 have been measured in two vibrational states (upsilon = 0 and 1) in the 5-24 GHz spectral region, using a cavity pulsed jet Fourier transform microwave spectrometer. The samples were prepared by ablating Sc metal in the presence of Br-2 contained in the Ar backing gas of the jet. The equilibrium internuclear distance r(e) has been determined along with estimates for the harmonic vibration frequency omega(e) and the dissociation energy, D-e. Nuclear quadrupole coupling constants and spin-rotation constants have been determined for both Sc and Br. The ionic character of the ScBr bond is estimated to be similar to 95\%. Magnetic shieldings for both nuclei have been estimated.},

	abstract = {The pure rotational spectrum of the free radical MgBr has been measured in its (2) Sigma(+) ground electronic state by Fourier transform microwave spectroscopy. Transitions have been observed for both (MgBr)-Mg-24-Br-79 and (MgBr)-Mg-24-Br-81 in the v = 0 and v = 1 vibrational states. Rotational and centrifugal distortion constants have been determined for each isotopomer in each vibrational state. Equilibrium rotational constants have been calculated and an accurate equilibrium bond length has been determined. Spin-rotation constants, for both the unpaired electron and the bromine nuclei, have been calculated along with magnetic and nuclear quadrupole hyperfine constants for the bromine nuclei. From these constants, the electronic structure of MgBr has been investigated and comparisons have been made to similar compounds. The unpaired electron spin density on the bromine nucleus has been found to be very small, suggesting that this is a very ionic compound. However, the Mg-Br bond has been found to have more covalent character than the bond in other alkaline earth monobromides. (C) 1997 American Institute of Physics. [S0021-9606(97)02046-1].},

	abstract = {The pure rotational spectra of the van der Waals dimers of Ne, Kr, and Xe with CO have been measured using a pulsed jet, cavity microwave Fourier transform spectrometer. All transitions measured were a-type R-branches, obeying selection rules Delta J=+1, Delta K-a=0, and Delta K-c=+1. Spectra with K-a=0 were measured for 7 isotopomers of Ne-CO, 13 of Kr-CO, and 17 of Xe-CO. Transitions with K-a=1 were measured for Ne-20-(CO)-C-12-O-16 and Kr-84-(CO)-C-12-O-16. Rotational constants and centrifugal distortion constants have been determined for all species, as well as the O-17 quadrupole coupling constants chi(aa) for Kr-84-(CO)-C-13-O-17 and Ne-20-(CO)-C-13-O-17. Effective structural parameters have been calculated from the rotational constants. Results derived from the O-17 quadrupole coupling constants and centrifugal distortion constants indicate that Ne-CO is considerably more flexible than Ar-CO, Kr-CO, or Xe-CO. Failure to observe hyperfine structure due to the Ne-21, Kr-83, and Xe-131 nuclei is discussed in terms of the weak rare gas-CO bonding. Comparisons have been made to the isoelectronic rare gas-N-2 van der Waals complexes. (C) 1997 American Institute of Physics.},

	abstract = {Pure rotational spectra of four different isotopomers of the dimer Ar-CO have been investigated between 8 and 18 GHz using a pulsed beam cavity Fourier transform spectrometer. The spectra confirm that the complex is a prolate near-symmetric rotor with an essentially T-shaped structure, and that it undergoes large amplitude zero-point motion. It is shown that on the average the argon is closer to the oxygen than to the carbon. The transitions measured obey a-type selection rules with DELTAJ = + 1, DELTAK(a) = 0, and DELTAK(c) = + 1. For Ar-40-(CO)-C-13-O-16, transitions have been observed for K(a) = 0 and 1 with lower state J values of 1, 2, and 3. For Ar-40-(CO)-C-13-O-16, and Ar-40-(CO)-C-13-O-18, a similar series was measured, but only for Ka = 0. For Ar-40-(CO)-C-13-O-17, the O-17 quadrupole hyperfine pattern was resolved in the rotational transition J(KaKc) = 2(02)-1(01). Determinations have been made for rotational and centrifugal distortion constants, as well as for the 170 quadrupole coupling constant chi(aa). Effective values have been obtained for the length of the line from the center of mass of the CO subunit to the argon nucleus, and for the angle between this line and the CO bond.},
