Theory of bridge-assisted electron transfer in systems with an intermediate link at high temperatures

From solution of the time-dependent wave equation by specifying the (t) function in the form of a linear combination a_i(t)_i+a_d(t)_d+a_j(t)_j (_i, _d, _j are the wave functions corresponding to localization of the electron on the donor, the intermediate link, and the acceptor), we obtain an expression for the electron transfer probability in a system consisting of six components: one direct transfer and five interference components. We have studied the effect of electronic structure and vibrational motion of the components of the system on the probability components. This has allowed us to find the dependence of the electron transfer probability on the ionization potential or the electron affinity of the intermediate link, playing the role of a catalyst or inhibitor of the process.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 25, No. 2, pp. 134–142, March–April, 1989.
