On the theory of Frenkel excitonic polarons Original Research Article

A theory of Frenkel excitonic polarons in molecular crystals is developed by applying two different methods of the diagonalisation of the exciton-phonon interactin Hamiltonian. The ground state energy and effective mass of Frenkel excitonic polarons are calculated through both methods and compared. The validity of the methods of diagonalisation for Frenkel excitons is discussed.
