Abstract

Ionization-loss stimulated Raman spectroscopy, a hole-burning technique, has been used to obtain size selective Raman spectra of Benzene (Ar)N Clusters (n=1−22) for the Benzene v1 and v2 totally symmetric vibrations. The spectra show both size and isomer specificity. The spectra are compared with the results of both experimental1 and throretical2 investigation of the Benzene (Ar)n 61 vibronic transiton. It is shown that the Raman spectra are consistent with the vibronic spectra and also provide new information about Ar salvation of the doped Benzene.
