Abstract：The Raman scattering coefficients of the fundamental ν1(992 cm-1) of C6H6 and the fundamental ν1(656 cm-1) of CS2 changed dramatically with relative concentration of the binary solution of CS2 and C6H6. The Raman spectra of the binary solution with different relative concentrations were measured. The results show that both the ν1 fundamentals intensities changed dramatically with the relative concentration of the solution and the fundamental ν1 of C6H6 has little effect on the Fermi resonance ν1+ν6～ν8. On the contrary, the change in the ν1 fundamental intensity of the CS2 changed which has more effect not only on the Fermi resonance ν1～2ν2 but also on the ν2 fundamental. In this report, the experimental results were analyzed based on the J. F. Bertran theory and group theory.
