Abstract/OtherAbstract:
Raman spectra of benzene, naphthalene and biphenyl have been taken up to a pressure of 13GPa. The results for benzene and naphthalene indicate that the perturbation of inter-molecular π-π stacking effect on the Raman intensity is neglectable. For biphenyl, all the Raman peaks show intensity enhancement during the compression process, which indicates the planar intra-molecular aromatic conformation play an important role in the intensity increments of Raman bands. For three aromatic compounds, C-H stretching vibration bands located at about 3000cm(-1) show intriguing intensity changes during compression account for the inter-molecular C-H⋯π interaction.
