摘要：
Results of C-13-NMR experiments on charge ordering in non-dimerized BEDT-TTF salts are discussed. It has been experimentally confirmed in theta-(ET)(2)RbZn(SCN)(4) that charge disproportionation already develops well above the metal-insulator transition temperature while no long-range charge order is stabilized. Dynamics of the charge fluctuations has been determined in this salt and compared with the situations in alpha-(ET)(2)I-3. This result seems to require a serious reconsideration of the transport properties in the metallic state.
