Abstract
Using the Onsager model, the effect of molecular orientation interactions in solutions on the rate constant of radiationless conversion of the energy of the excited S 1 state has been calculated for equilibrium systems with intramolecular charge transfer. The rate constant of the radiationless conversion of energy S 1 — X n is represented as a function of the polarity of the medium f(ε) = (ε − 1)/(2ε + 1), where is the permittivity of a solvent. The results obtained are compared with the Marcus theory and are also used to explain the well-known literature data on the influence of a solvent on the lifetime of the S 1 state of some carotenoids.
