Abstract

Optical Kerr effect spectroscopy has been used to study the orientational dynamics of benzene and benzene-d6 confined in nanoporous sol-gel glasses. Orientational diffusion was found to be inhibited considerably in confinement due to the strong wetting of benzene on silica. The orientational dynamics of benzene-d6 were found to be affected less than those of benzene, which is in agreement with the somewhat larger contact angle of benzene-d6 on silica. Comparison of our results to Raman data for confined benzene-d6 suggests that this liquid is considerably more organized at the pore surfaces than in the bulk.
