Depolarized Rayleigh scattering and orientational relaxation of molecules in solution. I. Benzene, toluene, and para-xylene

Abstract
Measurements of orientational relaxation rates of benzene, toluene, and para‐xylene in a variety of solvents have been made by depolarized light scattering. A plot of reorientational relaxation time of each solute versus solution viscosity was found to fit a straight line with nonzero intercept. The slopes of the lines are compared with those predicted by the Stokes‐Einstein relation.
