NMRRR elperunents, using field cyclin g, on pentamethylbenzene below 15 K yield one Zeeman-tunnel resonance anomaly in the spin-lattice relaxation, at 1.88 T, corresponding to a Larmor frequency equal to half the tunnel frequency, probably of methyl groups, whose reorientation causes the fi\* versus
