Popis:	The resolved chemical shielding anisotropy of 13C in solid benzene allows a study of nuclear spin relaxation for benzene molecules with different orientations. As expected from a simple theory, the relaxation is strongly orientation dependent due to the strongly anisotropic motion of the benzene molecule (which consists of reorientation about the hexad axis). Preliminary data are presented which exhibit quantitative agreement between theory and results for the 13C anisotropic nuclear spin-lattice relaxation and for the 13C anisotropic nuclear Overhauser enhancement on saturation of the proton resonance.
