The recently suggested increased mixing of Frenkel excitons and CT states in the neighbourhood of a charge is discussed. It is demonstrated that such mixing results in renormalization of the charge carrier hopping integral as it provides an additional channel of crystal polarization. The effect is expected to be highly anisotropic and different for electrons and holes. It is supposed to be especially important in the crystals of charge transfer complexes where the low‐lying excited states are present.
