title: Random walk models of electron tunneling in a fluctuating medium.
abstract: A modified approach to the electron transfer theory in disordered media is discussed by use of continuous time random walk models accounting for medium fluctuations. The models apply to the situations when the bridging medium between the donor and acceptor pair fluctuates changing coupling between intermediate transferring states. Effect of the latter on the long distance electron transfer is discussed pointing out emergence of nonexponential decay kinetics.
