ABSTRACT
The field of charge-transfer organic conductors has been the object of rapidly growing research activity for more than 30 years. Charge-transfer organic conductors are molecular solids which are characterized, first, by remarkably high electrical conductivity. Knowledge of the true dimensionality of the electronic system in such solids is an important prerequisite to an understanding of their electrical properties, which is, however, not always evident. It is a useful way, in practice, to look for phase transitions in organic conductors by means of the electrical conductivity data. Some structural parameters are more sensitive than others to this transition. The considerable electrical anisotropy of this salt is made still more evident on the room-temperature polarized infrared reflection spectra. Also, a general trend of the organic semiconductors is that the activation energy of the magnetic susceptibility is different from and significantly lower than the activation energy of the electrical conduction.
