What makes this reaction conceptually special is that there is no simple answer to this question. Rather, proton transfer should probably be described with respect to two coordinates The solvent reorganization energy that constituted the reaction coordinate of electron transfer reactions and the proton position between its two sites. On this two-dimensional free energy surface one coordinate (proton position) is quantum. The other (solvent reorganization) is essentially classical. This combination of higher dimensionality and mixed quantum and classical dynamics, together with the availability of an additional observable—the kinetic isotope effect associated with the reaction, make proton transfer a unique process. ...
