摘要: Abstract The cumulant expansion is used to derive two formally different master equations for a two-level molecular system interacting with bath, starting wit reduce the same form in markovian limit bath (where its correlation time much shorter than relaxation pr A detailed comparison made between predictions of approaches which enables us understand their range validity and limitations. We apply formalism vibrational dephasing impurity solid matrix obtain closed expression vib In contrast simple stochastic we predict that line shape non-markovian contains information regarding interactio However, fluctuations mean interaction energy if correlated frequency modulation, result
