Abstract
The primary charge separation in photosynthetic bacterial reaction centres (RC) is charactrized by three unique features: (i) Ultrafast rate in the psec domain which precludes energy waste due to back transfer to the antenna, (ii) non-Arrhenius temperature dependence of the rate, which manifests optimal coupling to the medium nuclear motion, and (iii) unidirectionality across the A branch of the quasisymmetric RC.KeywordsElectron TransferKinetic SchemeElectronic CouplingPrimary Charge SeparationSequential MechanismThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
