The Molecular Motion of Phenyl Groups in Toluene, Diphenylmethane and Triphenylmethane in Solutions of Carbon Tetrachloride by Raman Line Shape Analysis

Abstract
The reorientational correlation times of phenyl groups in the molecules of toluene, diphenylmethane, and triphenylmethane in carbon tetrachloride solutions were measured by the Raman-line-shape analysis. The reorientational relaxation times of the phenyl groups obtained increased in this order: toluene<diphenylmethane<triphenylmethane as a result of the increase in the mutual interaction among phenyl groups themselves in the molecule.
