	abstract = {Pure rotational spectra of seven isotopomers of Ne-OCS (Ne-OCS, Ne-22-OCS, Ne-21-OCS, Ne-(OCS)-O-18, Ne-(OCS)-C-13, Ne-(OCS)-S-34, and Ne-(OCS)-S-33) have been investigated using a pulsed jet cavity microwave Fourier transform spectrometer. Rotational and centrifugal distortion constants have been determined for all species, as well as the nuclear quadrupole coupling constants of S-33 and Ne-21 in Ne-(OCS)-S-33 and Ne-21-OCS, respectively. Harmonic force field analyses have been performed which account for the Variations in the distortion constants between the isotopomers. Effective and ground state average structures have been obtained and are discussed in light of the nuclear quadrupole coupling constants and of dipole moment measurements. The determined coupling constants have provided a means of comparing the effects of perturbation of the electronic structures of both constituents upon complexation. An electrostatic model has been applied to calculate the Ne-21 coupling constants and a possible source of their disagreement with experiment is discussed. (C) 1995 Academic Press, Inc.},

	abstract = {Pure rotational spectra of three isotopomers of the Van der Waals complex Ar-N-2 have been investigated in the frequency range 3.5-20 GHz, using a pulsed molecular beam cavity microwave Fourier-transform spectrometer. 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 = {The rotational spectrum of the van der Waals complex OCCl2 has been observed in the frequency range 5-12 GHz using a cavity-pulsed microwave Fourier transform spectrometer. The isotopomers investigated were (OCCl2)-Cl-35, (OCClCl)-Cl-37-Cl-35, (OCClCl)-Cl-35-Cl-37, (OCCl2)-C-13-Cl-35, (OCClCl)-C-13-Cl-37-Cl-35, (OCClCl)-C-13-Cl-35-Cl-37, and (OCCl2)-O-18-C-13-Cl-35. It is established that the complex is linear in the ground vibrational state, and a complete substitution (r(s)) structure has been obtained. The nuclear quadrupole hyperfine structures due to the Cl-35 and Cl-37 nuclei have been resolved, yielding the corresponding nuclear quadrupole coupling constants. The differences in these constants between the inner and outer Cl nuclei, along with the derived geometry and the relatively low centrifugal distortion constants, are consistent with a picture of a rather rigid complex with a significant charge redistribution in the Cl2 monomer on complexation with CO.},

	abstract = {The pure rotational spectrum of the van der Waals complex Ar-Cl2 has been observed between 5 and 14 GHz using a Balle-Flygare type pulsed molecular beam microwave Fourier transform spectrometer. Ten a-type rotational transitions of Ar-Cl-35(2), as well as five a-type rotational transitions of the mixed isotopomer Ar-(ClCl)-Cl-35-Cl-37, have been assigned. The rotational constants and quartic centrifugal distortion constants have been determined. Unlike its isovalent linear isomer Ar-CIF, Ar-Cl2 has been found to be a T-shaped complex. This confirms the result from electronic spectroscopy and is in accord with the atom-atom additive model. The distance from the Ar nucleus to the center of mass of the Cl2 subunit has been calculated to be 3.7190 angstrom for Ar-Cl-35(2) and 3.7184 angstrom for Ar-(ClCl)-Cl-35-Cl-37, respectively. The van der Waals stretch and bend force constants, as well as their corresponding harmonic vibrational frequencies, have been derived and compared with the theoretically predicted values. The nuclear hyperfine splittings due to the two chlorine nuclei have been resolved and the coupling constants have been accurately determined. For Cl-35 these are (in MHz): chi(aa) = 54.8180(16), chi(bb) = -110.7131(19), chi(cc) = 55.8951(19) in Ar-Cl-35(2); and chi(aa) = 54.8407(27), chi(bb) = -110.706(20), chi(cc) = 55.866(20) in Ar-(ClCl)-Cl-35-Cl-37. For Cl-37 the values are chi(aa) = 43.2111(29), chi(bb) = -87.267(12), chi(cc) = 44.056(12) in Ar-(ClCl)-Cl-35-Cl-37. A value has been obtained for the nuclear quadrupole coupling constant in free diatomic chlorine.},
