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 higher frequency side. Their characteristic shifts are discussed based on the structure of the clusters.
