Ab initio study of energies, structures and vibrational spectra of the complexes of water with carbon oxysulfide and nitrous oxide

The interaction energies, structures and vibrational band wavenumbers of the binary complexes formed between water and carbon oxysulfide, and water and nitrous oxide, have been predicted by means of ab initio molecular orbital theory. The results are discussed in the light of high resolution gas phase infrared and microwave, and matrix isolation infrared spectroscopic studies, and of previous theoretical calculations on similar and containing carbon dioxide complexes.
