摘要：

Direct observation is reported of cross-relaxation between isolated Ir 4+ ions in (NH4)2PtCl6 and exchange-coupled triads. A bimodal microwave cavity was used in the experiments and a small change in the electron paramagnetic resonance signal at 33·1 GHz due to triads was observed when the single ion resonance was saturated by a microwave pulse at 9·86 GHz. The results are in agreement with those of Harris and Yngvesson. Effects due probably to larger clusters were also observed.
