	abstract = {The rotational spectra of the fluorosulfate (FSO3 center dot) molecular radical in its vibronic ground state were measured in the millimeter-wave region and analyzed in detail using the matrix elements of the rotational, fine, and hyperfine Hamiltonian terms. The analysis of the assigned transition frequencies made it possible to derive very precise values of the rotational, centrifugal distortion and fine structure constants and to confirm the C-3v molecular symmetry of the vibronic ground state unambiguously. In addition, an effective parameter of the "A(1)-A(2) splitting" was determined. The rotational transitions of the FSO3 center dot free radical were observed, identified, and analyzed for the first time.},

	abstract = {New laser-induced fluorescence spectra of supersonic jet cooled acetylene (C2H2) in the wavelength region 230-205 nm have led to an improved understanding of the vibrational structure of the (A) over tilde (1)A(u) state. Among the new bands observed are two weak perturbed bands at 46008 cm(-1) and 46116 cm(-1). Rotational analyses of these bands, together with the corresponding {\textquoteright}hot{\textquoteright} bands arising from the ground state v(4) fundamental, have shown that the upper states have asymmetric top K structure that is unaffected by a axis Coriolis coupling; this means that they do not involve overtones of the low frequency bending vibrations and therefore must be combinations of a(g) vibrational normal modes. From their positions in the manifold, their vibrational assignments can only be 2(0)(2)3(0)(1) and 1(0)(1)3(0)(1). These assignments lead to values of x(22){\textquoteright}, x(13){\textquoteright}, and a revised value for the symmetric CH stretching frequency, v(1){\textquoteright} = 2880.5 cm(-1); this revised value is 160 cm(-1) lower than the previously accepted value, but consistent with new ab initio calculations that we performed at the EOM-CCSD level using a TZ2P ( triple-zeta plus double polarization) basis set.},

	abstract = {The microwave spectrum of phosphenous fluoride, OFF, has been measured using a pulsed-jet cavity Fourier transform microwave spectrometer. With the exception of a mass spectroscopic detection of the molecule, chemically prepared for use in a matrix IR study, this is the first observation of free gas-phase OFF. The samples were prepared from mixtures of PF3 and O-2 in Ne carrier gas, using an electric discharge. Rotational transitions of two isotopomers ((OPF)-O-16-P-31-F-19 and (OPF)-O-18-P-31-F-19) have been measured in the 4-26 GHz frequency range. The determined rotational constants have been used to calculate r(0), r(7), and approximate r(e) molecular geometries. In contrast to the nitrogen analogue, ONF, OFF has been found to show no irregularities in its geometry. Small hyperfine splittings due to the spin-1/2 P-31 and F-19 nuclei have been analyzed in terms of nuclear spin-rotation interactions. Because the determined coupling constants were of similar magnitudes and could not be unambiguously assigned, the related nuclear shielding parameters have been derived using both possible assignments. The spin-rotation coupling constants are compared with those calculated using ab initio techniques, and the F-19 nuclear shieldings are compared with those derived for the nitrogen analogue ONF.},

	abstract = {O-18-enriched, monolabeled perchloryl fluoride, (FClO2O)-F-19-Cl-35/37-O-16-O-18, has been synthesized. Its rotational spectrum has been studied in the 4-22 GHz region. In addition, the spectra of the symmetric isotopomers (FClO3)-F-19-Cl-35/37-O-16 have been reinvestigated. Rotational and centrifugal distortion constants, as well as chlorine nuclear quadrupole and chlorine and fluorine spin-rotation and spin-spin coupling constants, have been determined for the ground vibrational state. The ground state rotational data have been used to evaluate geometrical parameters. The harmonic force field has been refined. The results are compared with data of related molecules.
