摘要：

H-1 NMR measurement was performed for a single crystal sample of the organic Mott insulator kappa-(ET)2Cu2(CN)3 with a nearly isotropic triangular lattice. The I H NMR spectra and the spin-lattice relaxation rate, 1/T1, show no indication of magnetic transition down to 30 mK. However, the line shows a slight but gradual broadening accompanied with only a moderate increase m the spin-lattice relaxation rate, 1/T1, below 4 K. It suggests a possible change of spin dynamics of the frustrated quantum spins.
