Evaluation of franck-condon factors for nonradiative singlet-triplet transitions in aromatic molecules

  • M. Ya. Ovchinnikova


Dependence of the probability of nonradiative T → S transitions in aromatic molecules on electronic transition energy, temperature, and parameters relating the electronic excitation to molecular vibrations is investigated on the basis of general formulas for the probabilities of the transitions. An evaluation is made of the real parameters by means of the vibrational structure of the phosphorescence spectrum and the probability of T → S transitions in benzene, anthracene, naphthalene, and benzophenone.
