We also compute the diabatic electron transfer rates (k ET ) for the reactions, even though the strong coupling mostly motivates the adiabatic electron transfer path. In the absence of applied potentials and for molecules located closest to the electrode, low barrier reactions, those ∆A 0 IJ < 0.42, are extremely fast, while the remainders are very slow. When the potential wells of state I and state J become symmetric by applying an external potential, i.e.
