摘要: It is known that the diagonalization of exciton-phonon Hamiltonian gives rise to composite energy states. Within single phonon approximation, two different diagonalized Hamiltonians are obtained for 0–0 and 0–1 transitions in pure molecular crystals. The resulting secular equations solved, analytical expressions eigenvalues corresponding derived. thermal broadening due states interaction also calculated at low temperatures, results agree with experiments.
