WebApr 8, 2024 · The theory fully validates the fractional Wien mechanism, highlighting that this effect originates in an interplay between many-body dynamics of ion pairs and Coulomb gas statistics. This equation for gives satisfactory agreement with experimental measurements for low electrolyte concentrations, typically less than 10 mol/L. Deviations from the theory occur at higher concentrations and with electrolytes that produce ions of higher charges, particularly unsymmetrical electrolytes. Essentially these deviations occur because the model is oversimplified, so there is little to be gai…
