摘要：
The title compound undergoes a neutral-ionic (N-I) phase transition under pressure. In order to examine the electronic state of BEDT-TTF and ClMeTCNQ molecules separately by NMR,we prepared the complex with Cl,MeTCNQ and C-13, deuterium-substituted BEDT TTF molecules. The C-13 and H-1 NMR measurements were performed at ambient and applied pressures. Under 8 kbar, the N-I transition was found to be continuous. We also found that the I-phase is nonmagnetic state.
