- •
General characteristics of the rate constant of the non-adiabatic heterogeneous electron transfer are considered.
- •
A series of the extensions of the Marcus approximation is suggested and studied.
- •
The new approximate expressions for the rate constant of the non-adiabatic heterogeneous outer-sphere electron transfer are obtained.
- •
They have ≤ 1% error for all reaction free energies and realistic reorganization energies.
