	abstract = {The microwave spectrum of the unstable molecule sulphur difluoride, SF2, prepared via a pulsed electric discharge in an SF6/OCS mixture, has been measured using a pulsed jet cavity Fourier transform spectrometer. F-19 hyperfine structure has been resolved, and unusually small, negative values have been determined for two of the spin-rotation coupling constants. These constants have been used to calculate the 19F principal, inertial axis nuclear shielding components; the determined paramagnetic shieldings are also unusual and produce a large positive average shielding, sigma(av). The shieldings have been compared with the corresponding constants obtained for OF2, SiF2, and GeF2. The results for SF2 are consistent with values determined from earlier NMR experiments and ab initio calculations. The origin of the unusual shieldings has been found, and is discussed, using a semi-quantitative model, in terms of the geometry and the electronic energy level structure of the molecule.

	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 = {The pressure broadening and shifting coefficients for pure rotational transitions of CO in a He bath gas at very low temperatures are calculated from the best available potential energy surfaces, and compared with very recent measurements by M. M. Beaky, T. M. Goyette, and F. C. De Lucia [J. Chem. Phys. 105, 3994 (1996)]. The results obtained for two recent empirical potentials determined from fits to Van der Waals spectra, and for a recent high quality purely ab initio surface, are consistent with one another. The best of the spectroscopic potentials also yields good agreement with high temperature virial coefficients and transport properties. Predictions from all three of these potentials agree with linebroadening and shifting measurements at temperatures above similar to 20 K, but are in substantial disagreement with the measurements at temperatures below 4 K. At present, the source of this discrepancy is not known. (C) 1996 American Institute of Physics.},

	abstract = {The nu(2) infrared fundamental of the transient molecule formyl chloride, HCOCl, has been recorded at high resolution. Detailed assignments of the rotational structure have been made for both HCO Cl-35 and (HCOCl)-Cl-37. The nu(2) band, whose origin is at 1784.1377 cm(-1) in (HCOCl)-Cl-35, is predominantly A type with a very weak B-type component. Numerous excited state perturbations occur throughout the band, caused mainly by Δ K-a\=2 Fermi resonance and Δ K-a\=1 Coriolis interactions with the 3(1)5(1) vibrational state. Even though no {\textquoteright}{\textquoteright}extra{\textquoteright}{\textquoteright} lines resulting from the perturbations could be assigned, a complete analysis of the perturbed rotational structure has been possible. Accurate molecular constants for both the {\textquoteright}{\textquoteright}bright{\textquoteright}{\textquoteright} perturbed 2(1) state and the {\textquoteright}{\textquoteright}dark{\textquoteright}{\textquoteright} 3(1)5(1) perturbing state have been obtained, using a Hamiltonian which includes both the Fermi and Coriolis interactions; only two interaction parameters are needed, one for each mechanism. Further perturbations at high K-a are assigned to Coriolis interactions with the 5(2)6(1) level.},

Rotational constants and quartic and sextic centrifugal distortion constants have been obtained, along with N hyperfine constants. The spectra of Ar-N-14(2) and Ar-N-15(2) indicate equivalence of the nitrogen nuclei, and thus confirm C-2v symmetry for the complexes. The measured transition frequencies and the derived constants have been used to test the best available literature potential-energy surfaces for the Ar-N-2 interaction. For this purpose rotational transition frequencies and expectation values of other properties were calculated and compared with the corresponding values from the microwave experiments. A refined version of one of the surfaces has been generated by inclusion of the microwave results.},

	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.},
