The correlations between the Raman band intensities, concentrations, refractive indices and the absorption frequency of benzene were studied by measuring the integrated intensities of the Raman band 992 cm-1 of benzene in 8 solutions of different concentrations and the refractive indices of the solutions. It is shown that the intensity deviation is proportional to the difference between the refractive index of the solution and that of pure benzene. The band intensities of different solutions depend linearly on their refractive indices, that is, the intensity does not depend on the nature of the solvent, but on its refractive index. The relationship between the band intensities and the resonance frequency factors of benzene in the solutions is also linear. The experimental results are discussed from the point of view of perturbation of the medium on the electronic absorption band.
