The conduction mechanism of the crystals of tetracyanoquinodimethan (TCNQ) anion radical salts is studied. Unpaired π-electrons in TCNQ− anions are described by the Hubbard model with a narrow band and one electron per molecular site. The electronic spectra of the Hubbard model are determined by the Hubbard’s third solution. The value of the electrical conductivity of TEA(TCNQ)2 at 23°C agrees with experimental values quantitatively.
