Sažetak
A detailed theoretical description of the "resonance treatment" based on Bloch equations is presented for a dissipative two-state system, in the limit of weak coupling between a microscopic subsystem and its environment, using the framework of the "spin-boson" model. For an Ohmic spectral density function, the dynamics of the transition probability for an overdamped regime is applied in the case of the primary electron transfer reaction in a bacterial photosynthetic reaction center.
