H NMR spectra of hexamethylbenzene (HMB) in proionated crystalline and amorphous matrices at low temperatures are presented. All spectra reveal lineshape changes which can be attributed to methyl group tunnelling. Compared to neat HMB, a drastic increase of the tunnelling frequency is found for all

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
