摘要：
Diamagnetic susceptibilities of various kinds of activated carbon fibers (ACFs), nonporous carbon black, and Grafoil were measured under an N2 atmosphere in the temperature range of 273 to 423 K. An empirical relationship between the diamagnetic susceptibility and molecular structure was derived from the literature for polynuclear aromatic compounds without hydrogen atoms. The unit size of graphitic crystallites in ACFs was evaluated from the derived relationship.
