The Raman spectrum of chemisorbed benzene and deuterated benzene has been measured in the frequency range of 200–3400 cm −1 in backscattering geometry. In order to suppress the strong second‐order light‐scattering spectrum of glass, a difference Raman scattering cell has been developed. The vibrtational bands are shifted only slightly compared with liquid benzene. Additional bands are found, which are symmetry forbidden in free benzene. These bands result from symmetry lowering produced by the site symmetry of the surface. Compared with the Raman spectrum of liquid benzene, the vibrational bands of chemisorbed benzene are strongly enhanced.
