Single charge transfer, Marcus theory

Excited State Charge Transfer. Our goal here is to discuss aspects of ET theory that are most relevant to the charge transfer processes of excited molecules. One important point is that often the solvent relaxation is not well modeled with a single t, but rather a distribution of times apply. This subject has been treated by Hynes [63], Nadler and Marcus [65], Rips and Jortner [66], Mukamel [67], Newton and Friedman [68], Zusman [62], Warshel [71], and Fonseca [139], We also would like to study ET in the strongly adiabatic regime since experimental results on BA indicate this is the correct limit. Finally, we would like to treat the special case of three-well ET, which is the case for BA. 

The research groups of Lewis and Wasielewski estimated the rate constants of the charge separation (kcs) and recombination (kcR) between the nucleobase, which acts as the electron donor, and the electron acceptor at the loop position of the DNA hairpins, and also investigated the free energy dependence of the electron transfer rate. " It was found that the single-step electron transfer in DNA mediated by nucleobases can be described by the Marcus theory (4) developed for nonadiabatic electron transfer system. 

Owing to the efforts of scientists in the past two decades, detailed mechanisms of the charge transfer in DNA became clearer. It was revealed that the basic mechanisms for charge injection and single-step charge transfer can be described by the Marcus theory, indicating that the interaction between the donor and the acceptor involved in...
