	abstract = {The rotational spectrum of sulfur choride fluoride, ClSF, has been observed for the first time in the frequency range 8-26 GHz by means of a pulsed molecular jet Fourier-transform microwave spectrometer. The unstable sample molecule has been prepared using a pulsed electrical discharge in jets containing a mixture of SF6 and SCl2 in Ne. Besides the parent species (ClSF)-Cl-35-S-32-F-19, the isotopomers (ClSF)-Cl-37-S-32-F-19 and (ClSF)-Cl-35-S-34-F-19 could be observed in natural abundance. Rotational constants and quartic centrifugal distortion constants as well as nuclear quadrupole coupling constants due to Cl-35 and Cl-37 and spin-rotation constants due to Cl-35, Cl-37, and F-19 are given. The data were used for the determination of r(0), r(Delta P), r(s) structural parameters. Additionally, the new data were used for the refinement of the molecular harmonic force field. Results from those harmonic force field calculations were applied in the evaluation of the ground-state average structure, r(z), and the estimation of the equilibrium structure, r(e). The r(s) structure is r(SF)=160.653(162) pm, r(SCl)=199.437(65) pm, and angle(ClSF)=100.732(81)degrees. The diagonal elements of the Cl-35/Cl-37 quadrupole coupling tensors have been obtained, and are interpreted in terms of the bonding at Cl-35/Cl-37. Negative F-19 spin-rotation constants suggest a close analogy of the electronic structures of CISF and SF2. (C) 1997 American Institute of Physics.},

	abstract = {The rotational spectrum of the most abundant isotopomer of thionyl chloride, S-32 O-16 Cl-35(2), has been recorded in the frequency range 7.8-24.7 GHz using a pulsed molecular-beam microwave spectrometer. 262 lines of 27 rotational transitions (b- and c-type) have been used to determine rotational and quartic centrifugal distortion constants and the complete Cl-35 nuclear quadrupole coupling tenser, as well as spin-rotation coupling constants. Whereas the diagonal quadrupole coupling constants in the inertial axis system agree with those from previous microwave studies, disagreement is observed for the principal values chi(zz) (-63.8 MHz) and eta (-0.0143). However, the value of chi(zz) is in good agreement with those derived from solid-state NQR measurements. The centrifugal distortion constants together with vibrational wavenumbers and amplitudes have been used to refine the harmonic force field. The principal quadrupole coupling constants and the force constants are compared with those of related molecules, and the latter have been used to propose a reassignment of two vibrational bands of the related molecule, SO2Cl2.},

	abstract = {The pure rotational spectrum of sulfuryl chloride fluoride, SO2CIF, has been investigated in the frequency range 5.6-24.0 GHz using a pulsed molecular beam microwave Fourier-transform spectrometer. Between 48 and 170 lines of 8 to 26 rotational transitions have been observed for the six isotopomers SO2CIF, SO2 (CIF)-C-37, (SO2CIF)-S-34, (SO2)-S-34 (CIF)-C-37, SO (OCIF)-O-18 and (SOOCIF)-O-18-C-37 (unlabelled atoms indicate O-16, F-19, S-32 and (CI)-C-35) in natural isotopic abundance. The rotational and quartic centrifugal distortion constants have been determined, r(O), r(Delta P) and r(S)-type structural parameters have been evaluated. A harmonic force field has been calculated to derive ground-state average and estimated equilibrium geometries. The description of the normal modes in terms of internal coordinates is discussed. Chlorine and fluorine hyperfine structures have been resolved, allowing quadrupole coupling (including chi(bc) for the isotopomers containing O-18) and spin-rotation constants to be determined. Variations in the chlorine quadrupole coupling constants with different isotopomers have allowed the CI quadrupole tenser to be diagonalized and indicate that its z-axis coincides with the SCI bond.},
