Electrochemical Adiabaticity Parameter. Medium Dynamics vs. Static Distribution

4 ELECTROCHEMICAL ADIABATICITY PARAMETER. MEDIUM DYNAMICS VS. STATIC DISTRIBUTION 

The first two points were discussed in detail in Section 34.1. The third one is also of great importance. This can be seen from the following discussion. Let us consider a certain static polarization value at which the level is located just above the Fermi 

Only if one takes into account the solvent dynamics, the situation changes. The electron transfer from the metal to the acceptor results in the transition from the initial free energy surface to the final surface and subsequent relaxation of the solvent polarization to the final equilibrium value Pqj,. This brings the energy level (now occupied) to its equilibrium position e red far below the Fermi level, where it remains occupied independent of the position of the acceptor with respect to the electrode surface.
