A derivation of the classical Enskog and Boltzmann equations appropriate to rigid ovaloids is given. The Chapman-Enskog method for obtaining solutions to these equations is outlined;Gas phase studies of (1) Senftleben-Beenakker effects in simple systems composed of symmetric top molecules, and (2) chiral molecules in the presence of an external magnetic field are carried out. Also, results of liquid phase studies of (1) orientational relaxation phenomena in atom-diatom fluids, and (2) shear-orientational couplings in simple diatomic fluids, as measured by the Rytov parameter obtained from Depolarized Light Scattering, are reported;Finally, the pseudo-Liouville formalism is generalized to rigid ovaloids. This formalism is then utilized for the analysis of the effects of chattering on the Boltzmann bracket integral for rigid ovaloids; *DOE Report IS-T-1051.
