Abstract :
We have measured the temperature dependence of the spectrum and the spin-lattice relaxation time T1 by 2D nuclear-magneticresonance (NMR) for α-(h8-ET)2ND4Hg(SCN)4 and 1H-NMR for α-(d8-ET)2NH4Hg(SCN)4 in order to clarify the molecular dynamics of the non-centrosymmetric ND4+ and NH4+ ions. Both the systems show the peak in T1−1 around 40 K explained by Bloembergen-Purcell-Pound model, while the temperature dependence of the spectra were quite different.
