Results of NMR studies of the nuclear spin-spin relaxation times at low temperatures are reported for commensurate monolayers of 3 He physisorbed on hexagonal boron nitride. Temperature independent relaxation rates are observed for 0.11< T <0.56 K, and are interpreted in terms of the quantum exchange motions of the 3 He atoms. The relaxation times and the inferred effective exchange rates were observed to change significantly on replacing the 3 He atoms with relatively immobile Ne atoms. This result is understood in terms of a large 3-spin exchange in addition to 2-spin exchange.

The Doolan-Hacobian n.q.r. double pulse detection technique is described for the measurement of n.q.r, apparent spin-spin relaxation times as applied to a v.h.f. lecher line super-regenerative spectrometer. Results are presented for the linewidths of the 79Br and 81Br resonances in p-dibromobenzene. It was found that crystal-field inhomogeneities produce significant broadening of the n.q.r. signal.
