Abstract
Ab initio calculations at the MP2/6-31 + G(d,p) level of theory have b een carried out to determine the structure and vibrational spectrum of two hydrogen-bonded complexes, HBr:3,5-dichloropyridine and HBr:3,5-d ichloropyridine:2Ne. The presence of the two Ne atoms leads to dramati c structural and spectral changes. The computed HBr:3,5-dichloropyridi ne:2Ne spectrum exhibits strong low-frequency bands, in agreement with the experimental spectrum of HBr:3,5-dichloropyridine obtained in an Ar matrix.
