Abstract

We report on the $^{13} C$ spin-lattice relaxation times in polycrystalline fullerite $C_{60}$ measured over the temperature range 295–1000 K. At temperatures above 470 K, spin-lattice relaxation is dominated by the spin-rotation interaction. From an analysis of temperature dependence of $T_{1} (^{13} C),$ the spin-rotation constant is determined using J and M models of rotational diffusion: $C_{J} ≃ - 51 Hz$ and $C_{M} ≃ - 29 Hz .$
