	abstract = {The pure rotational spectra of low lying v=0 and 1 vibrational levels of the (2)Sigma (+) ground states of several isotopomers of YbF, YbCl, and YbBr were recorded using a pulsed jet cavity Fourier transform microwave spectrometer. Through least squares fits, parameters describing rotational, fine, and hyperfine effects (such as Fermi-contact, dipole-dipole coupling, and nuclear spin-rotation coupling) are presented. Trends in this halide series show an increasing amount of unpaired spin-density on the halide nucleus with increasing halide atomic number, which is consistent with results obtained in previous studies of the calcium analogs. Effective equilibrium bond lengths for (YbF)-Yb-174 and (YbCl)-Yb-174-Cl-35 have been determined to be 2.016 514(1) Angstrom and 2.488 285(1) Angstrom, respectively. The spectra of the two major bromine isotopomers, (YbBr)-Yb-174-Br-79 and (YbBr)-Yb-174-Br-81, were studied only in the v=0 level, and the derived values of r(0) are 2.647 364 5(2) Angstrom and 2.647 347 6(2) Angstrom, respectively. The uncertainties in the equilibrium bond lengths of YbF and YbCl are discussed in terms of the measurement accuracies of the spectra and of the Born-Oppenheimer approximation.

	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.},
