Identification of Products of Merocyanine 540 Decay by Photolysis and Thermolysis

Аннотация

Possible products of merocyanine 540 decay are studied using quantum-chemical calculations. The results of calculation are compared with experimental investigations of the spectral-luminescent properties, and the products of photo- and thermodecay of the merocyanine 540 molecule in water are identified. It is shown that different products are formed by thermolysis (decay in the ground electronic state S0) and photolysis (decay in an excited electronic state).
