Abstract

Within the Redfield theory, a model is proposed that describes dissipative dynamics of electronic excitation energy migration in natural and artificial photosystems. The model explicitly takes into account physicochemical properties of the protein environment, which allows the fitting parameters to be completely excluded from calculations. The model is used to calculate the dynamics of energy transfer in a photosystem of purple bacteria and eight model photosystems, which helped to reveal the main factors that determine the rate and efficiency of energy transfer.
