Structural relaxation of excited molecules of heteroaromatic compounds

摘要

The results of investigation into structural relaxation in the excited singlet state are summarized for a wide range of heteroaromatic fluorophores and some of the heteroaromatic cations. Particular attention is paid to the substantiation of the modern competitive models of structural relaxation (TICT and PICT). The spectral-and-kinetic parameters of the compounds and the rate constants for the formation of relaxed charge-transfer states are tabulated.
