Characterization of the electronically polarized environment and the nuclear relaxation that accompanies charge carriers is fundamental to charge transport in crystalline, polycrystalline, and amorphous organic solids. To study the polarization effects of localized charged carriers, we use quantum/classical QM/MM approaches with charge redistribution and polarizable force field schemes and apply them to crystals of naphthalene through pentacene. We describe the results of a comprehensive investigation of the electronic polarization energies in molecular crystal structures of these oligoacenes and discuss as well the evolution of the nuclear relaxation energies calculated for model oligoacene systems.
