Relaxation calculations for rapidly spinning samples show that spin-lattice relaxation time (T 1Z ) anisotropy varies with the angle between the rotor spinning axis and the external field. When the rate of molecular motion is in the extreme narrowing limit, the measurement of T 1Z anisotropies for t

A transient nuclear Overhauser effect (NOE) makes measurements of the 13C spin-lattice relaxation times in organic solids complicated. Extended Solomon equations are applied in order to describe 13C spin-lattice relaxation with 'H r.f. field irradiation. Spin-lattice relaxation under r.f. irradiatio
