Abstract
The frequency () and temperature () dependent conductivity () is reported for cis-, trans-, and ammonia-compensated . A strongly -dependent dc together with a weakly -dependent ac were observed for predominantly cis- and for N-compensated samples, similar to of many semiconductors. The trans- has a larger "weakly" -dependent dc and anomalous strongly -dependent ac . The latter results are in good agreement with Kivelson's theory of charge transport via intersoliton electron hopping.
