✦ Synopsis

The interpretation of molecular reorientations in liquid benzene has been largely unsatisfactory because isotropic reorientation is usually assumed. By analyzing Raman line shapes and ZD NMR relaxation times as a function of temperature. a picture of highly anisotropic molecular reorientation emerges. Rotation about the symmetry s.yis ap pears to be consistent with a slightly damped fret rotation model of diffusion whereas the rotational motion perpendicular to the Cg axis can best be interpreted in terms of a small-step brownian rotation model.
