Electron spin polarization of the oxidized primary electron donor in reaction centers of photosynthetic purple bacteria

Abstract:

Fast time-resolved EPR spectroscopy is used to study electron spin polarization (ESP) in perdeuterated native, Fe2+-containing reaction centers (RCs) of photosynthetic purple bacteria. The spin-correlated radical pair(SCRP) model (previously used to simulate ESP observed in Fe-depleted RCs (Höre, P. J.; Hunter, D. A.; McKie, C. D.; Hoff, A. J. Chem. Phys. Lett. 1987, 737, 495) is extended to include the large anisotropy arising from the magnetic interactions between Fe2+ and the reduced prima...
