摘要：
Present status of experiments on charge ordering (CO) phenomena observed in organic molecular conductors is reviewed. Experimental techniques to detect and analyze the CO, i.e., NMR, X-ray and Infrared/Raman spectroscopy, are described and the experimental results in typical materials exhibiting CO are summarized. (DI-DCNQI)(2)Ag, (TMTTF)(2)X, alpha-(BEDT-TTF)(2)I-3, theta-(BEDT-TTF)(2)RbZn(SCN)(4) and related materials are discussed. Charge disproportionation without long-range order observed in numbers of materials are also included.
