23. 0. However, this approach is not supported by MD calculations.
24. It is noteworthy that individual model-free fits to all sets of data (3 × 3 = 9), for example, by a three-parameter VTF-type function, would require 9 × 3 = 27 parameters to be adjusted in total.
25. The present experiments under equilibrium conditions should be distinguished from limiting-current measurements across an electrochemical cell, which involve field-driven migration effects. In the later case, the Grotthuss mechanism may, in principle, enhance the charge-transfer efficiency.
