	abstract = {The pure rotational spectrum of palladium monocarbonyl. PdCO, has been measured between 6000 and 24 000 MHz using a cavity pulsed jet Fourier transform microwave spectrometer. The molecules were prepared by laser ablation of Pd in the presence of CO contained in an Ar backing gas. The spectra of 15 isotopomers have been used to determine the molecular geometry from the measured rotational constants. Centrifugal distortion constants are in good agreement with those calculated from a literature harmonic force field. A nuclear quadrupole coupling constant and nuclear spin-rotation constant have been determined for Pd-105. Nuclear shielding parameters have been evaluated from the measured spin-rotation constant. The geometry is discussed with reference to theoretical data and to other molecules containing an M-CO bond.},

	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 = {High-resolution rotational spectra of InF, InCl, and InBr have been measured with a pulsed jet cavity Fourier-transform microwave spectrometer. Samples were prepared by vaporizing In with a pulsed Nd:YAG laser, and reacting the vapour with a precursor gas entrained in the Ne backing gas of the jet. Precise rotational and nuclear quadrupole coupling constants have been obtained for all these molecules, along with the first nuclear spin-rotation constants of InCl and InBr. The hyperfine coupling constants are discussed in terms of the electronic structures of the molecules.},
