This chapter presents the so-called dielectric theory of the Frenkel excitons. The theory is the generalization of the local field Lorentz theory to the case of anisotropic molecular solids. It takes into account the local field corrections which determine the difference between lthe ocal and mean (Maxwell) electromagnetic field and allow for the calculation of the dielectric tensor for anisotropic crystals. The theory is applied to perfect and also to mixed crystalline solutions and crystals with impurities. It is shown how not only the transition dipoles but also the higher multipoles can be taken into account.

Keywords:   dielectric tensor, local field method, local field corrections, local electromagnetic field, mean electromagnetic field, anisotropic crystals, mixed crystalline solutions, impurities, higher multipoles
