| Abstract: | Low frequency intermolecular vibrations of benzonitrile-(H2O)n = 1 - 3, -(CH3OH)n = 1 - 3, and -(CHCl3)n = 1 - 3 clusters were observed by stimulated Raman - UV double resonance spectroscopy combined with fluorescence detection. The Raman
active vibrations, which appear in the region from 5 to 50 cm-1, exhibit characteristic frequency shifts depending on the cluster structure and on the cluster size. In benzonitrile-(H2O)n = 1 - 3 and -(CH3OH)n = 1 - 3, the lowest frequency band showed a lower frequency shift with an increase of the number of solvent molecules. On the other
hand, that of benzonitrile-(CHCl3)n = 1 - 3 showed a shift to the higher frequency side. Their characteristic shifts are discussed based on the structure of the clusters.
