- Abstract
- The energy transfer from accessory bacteriochlorophyll molecules (B) to the special pair (P) in the reaction center of Rb. capsulatus and Rb, sphaeroides R26 has been time-resolved using 23 fs pulses. In both reaction centers, the B* transient bleaching decays biexponentially, with a fast component of approximately 100 fs which gives a characteristic time scale for excitation energy transfer from B* to P. In Rb. capsulatus, the amplitudes for this component and a 360 +/- 40 fs decay of uncertain origin reported in previous experiments are approximately equal. Several models for the two components are discussed.
