Abstract
The structure, energetics, and vibrational properties of complexes for med between H2S and CO have been investigated by matrix isolation FTIR spectroscopy and ab initio molecular orbital theory. Two stable compu tational minima were found representing nearly linear hydrogen bonds b etween the subunits. The H2S-CO and H2S-OC species were calculated to be bound by 5.22 and 1.54 kJ mol(-1), respectively. The computational results were reproduced by experimental assignments for the carbon att ached complex, The stretching vibrations of the complex subunits were found to be similarly perturbed upon complexation both experimentally and computationally.
