## Abstract The geometries of the dimer, trimer, and tetramer hydrogenβbonded clusters of water, methanol, and ammonia molecules have been derived using previously published intermolecular pair potentials containing constants optimized from __ab initio__ calculations. The lowest energy forms for th
The formation enthalpy, the frequency shift and integrated intensity of the '.'OH stretching vihration have heen determined for hydrogen bonded complexes formed between phenol derivatives and tetramethylthiourea or dimethylthioformamide. These data are compared with comnlexes involving carhonyl hase
