Recent solid-state NMR studies have shown that the nuclear spin-lattice relaxation time of C60 is dominated by the chemical shift anisotropy relaxation mechanism. Those studies were performed at high magnetic field strengths and at temperatures not exceeding 320 K. We find that the spin-rotation relaxation mechanism contributes significantly to the total relaxation rate at low magnetic field strengths. This relaxation mechanism also becomes significantly at high temperatures for high magnetic field strengths. We find that the average value of the spin-rotation coupling constant is equal to 41 Hz.
