摘要：

C-13-NMR measurements have been carried out on the quasi two-dimensional organic conductor, alpha-(BEDT-TTF)(2)I-3. We measured the angular dependence of C-13-NMR spectrum at several temperatures above metal-insulator transition temperature, 135 K (=T-MI). We found that charge (spin) disproportionation already exists in the metallic state and gradually develops as temperature approaches to T-MI.
