本文用NMR和NMR研究了由单分子物种组成的分子导体（Pt）. NMR位移和弛豫速率的温度依赖性提供了具有明显电子相关性的金属性质的微观证据。这两种化合物在很宽的温度范围内都表现出反常的频率依赖性核自旋-晶格弛豫速率的增强。这些观测结果表明，在低能激发下存在着异常的分子运动。
The molecular conductors(, Pt) consisting of single molecular species are investigated withNMR andNMR. The temperature dependences of theNMR shift and relaxation rate provide microscopic evidence for the metallic nature with appreciable electron correlations. Both compounds exhibit an anomalous frequency-dependent enhancement in thenuclear spin-lattice relaxation rate in a wide temperature range. These observations signify the presence of extraordinary molecular motions with low energy excitations.
