Molecular Reorientational Motion of the Benzene Molecule in a Mixture of Benzene with Carbon Tetrachloride by Raman Band Spape Analysis

Abstract

The reorientational correlation times of the benzene molecule in mixtures of benzene with carbon tetrachloride were measured by the method of the Raman line shape analysis. The reorientational relaxation times τ_or of C₆H₆ in solutions increased with increasing mole fraction of CCl₄. Information was also obtained on an intermolecular vibration-vibration energy transfer process which primarily affects the mean life time of the first excited vibrational state ν₂ (a_1g) in benzene in solutions.
