| Abstract: | Conclusion In the present study we investigated the kinetics of the initial charge separation and energy transfer in the PS II reaction
center using pico-second and femto-second time-resolved techniques. We conclude that there are energy transfer processes between
?-Car or Pheo and P680 in the PSII reaction center. The time constant of energy transfer from Pheo to P680 is less than 100
ps, while that from (?-Car to P680 is about 350 ps. For the initial charge separation in the PS II reaction center, the preliminary
finding supported the about 3-ps time constant of charge separation. The possible kinetic scheme in PS II reaction center
was proposed. Further experiments are in progress. |
