The resonance Raman effect has been applied for the first time to the study of the structure of adsorbed molecules and the interaction between adsorbents and adsorbates. By rotating a sealed sample and using Ar + laser excitation, the resonance Raman spectrum of I 2 adsorbed on the silicas was measured for the second to the fifth harmonics. The peak frequencies were slightly shifted from those for the gas molecule, indicating the weak bondage between the surface OH groups and iodine molecules. When iodine monochloride was adsorbed on a silica surface, the resonance Raman spectrum of I 2 adsorbed on silicas was also observed.
