The influence of the energy parameters of donor-acceptor complexes on transient absorption dynamics of charge transfer state

Transient absorption dynamics and the charge transfer state depopulation dynamics of the donor-acceptor complexes have been calculated at the polar solvent. The influence of the reorganization energy and the free energy gap on the transient absorption rate decay has been analyzed for the electron transition from the charge transfer state to the high excited state. For a solvent with the single relaxation mode it has been shown that the variation of the carrier frequency of the pump pulse does not affect the transient absorption dynamics and changes the charge transfer state depopulation dynamics.
