The electron-vibrational model for the organic dimer proposed in this paper allows to take into account not only the electron correlation (the organic charge transfer complexes are strongly correlated systems) through the dimerized Hubbard model, but also the internal structure of the dimer and each of its monomers by introducing of the additional term into the Hamiltonian for describing the interaction of electrons with vibrational subsystem. Thus, it provides ample opportunities to describe in detail the polarization and conduction properties of organic dimer systems.
