A temperature dependence of a constant of a singlet-triplet transition rate of naphthalene molecules in glassy toluene

The probability temperature dependence (77-120 K) of a naphthalene molecules transition to the triplet state has been found. The transition occurs as a result of energy transmission by benzophenone molecules. This dependence is shown to be conditioned by temperature influence on migration efficiency of electronic excitation energy over the levels of benzophenone (the energy donor).
