Low frequency intermolecular vibrations of benzonitrile-(H2O), -(CH3OH), and clusters were observed by stimulated – UV double resonance spectroscopy combined with fluorescence detection. The 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) and -(CH3OH), 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) showed a shift to the higher frequency side. Their characteristic shifts are discussed based on the structure of the clusters.
