Abstract
C-13 NMR measurements have been carried out to investigate the nature of th e electronic state of the one-dimensional half-filled band system, (TTM-TTP )I-3. Metal-insulator transition at around 120 K was observed through the t emperature dependence of NMR relaxation rate, 1/T-1. From the analysis of N MR spectra in the insulating state, it is strongly suggested that charge di sproportionation with the valences of the TTM-TTP molecules 2-0-2-0 exists along the stacking axis.
