Abstract
The model of independent graphite subsystems is extended to describe the electronic states in stages 3 and 4 of GAC. The electrostatic effects related to the nonequivalence of the internal and external graphite layers are proved to induce a non uniform charge distribution in the system, and also to modify drastically the band structure. Interband optical transitions are analysed within this model. With a charge transfer coefficient comparable to the value obtained for lowest stages of GAC, the expected energies of the intervalence transitions are close to the energies of the reflectivity structures observed experimentallyKeywords
