A Magnetic View of the Reaction Center
The understanding of natural photosynthesis has advanced steadily in the last twenty years such that the synthesis of artificial photo-electron transfer devices is now occurring. Even so, our understanding of the natural process of photosynthesis is far from complete. Magnetic resonance has played a crucial role in establishing the current understanding of the primary events of photosynthesis. EPR, ENDOR, RYDMR and MARY experiments on radicals, radical pairs, and triplets have provided much of the background for connecting the x-ray structure provided by Michel, Deisenhofer and Huber to the function of the various components of the bacterial reaction center. Previously, we have shown that the triplet of Rp. viridis is highly localized on one half of the special pair whereas the triplet of Rb. sphaeroides is highly delocalized such that the triplet of the special pair has approximate C2 symmetry.
