Abstract ： The energy transfer pathways from the excited accessory* ) within native and modified (pheophytin-exchanged) reaction center isolated from Rhodobacter* decays with time constant of 240 fs, followed by a partial recovery of the ground state bleaching with time scale of about 2 ps. In modified RS601(Phe), however, B* decays with time constant of 800 fs for magic angle (54.7°) polarization configuration. In addition to the general assumption of energy transfer pathway from B* to the special pair P, an alternative pathway for energy transfer probably operates as well.
