    • (a) In the theoretical work of ref. 316, the authors instead postulated that the PT coordinate in CEP does not contribute to the inner reorganization energy, but calculated a larger outer reorganization energy for CEP compared to a pure ET. We do not agree because the nuclear coordinates are likely to change with deprotonation, to allow for proton tunneling:
