Abstract
We report for the first time the vibrational spectrum of a molecular anion−water complex in which the water molecule adopts a symmetrical binding motif. In the specific complex considered, S ·H2O, each hydrogen atom is attached to one of the oxygen atoms of the anion. The vibrational spectrum is rather simple and is analyzed with the aid of isotopic substitution and ab initio calculations of the complex structure and harmonic vibrational frequencies. The symmetric and asymmetric OH stretching modes in the S ·H2O complex are much closer in energy than in the isolated water molecule, an effect that is traced to the reduction in the HOH angle of the water molecule upon complexation.
