ELECTRIC-DIPOLE MOMENTS OF RARE-GAS CARBONYL SULFIDE VAN-DER-WAALS COMPLEXES

The μa and μb electric dipole moment components of the Ne-OCS, Ar-OCS, and Kr-OCS van der Waals complexes were determined using Fourier transform microwave spectroscopy. The accuracy of these results was evaluated by comparing the Ar-OCS moments with molecular beam electric resonance measurements. The experimental moments are compared with values calculated from projections of the dipole moment of the OCS monomer, corrected for effects from harmonic bending and induced dipole moments in the rare gas atoms. The μa and μb components were reproduced within 0.01 D for the Ar and Kr complexes and within 0.02-0.025 D for the Ne complex. © 1993 Academic Press, Inc.
