3. The terminology in this area is in flux. "CPET", coined by Costentin et al., (2b) refers to any process in which electron and proton transfer are in the same kinetic step. The traditional term HAT is, in our view, (1c, 2c) best used to include all reactions in which electron and proton transfer from one reactant to a single product. There are also narrower definitions of HAT, for instance, restricting it to processes "in which the transferring electron and proton come from the same bond". (1b) Reaction (1) is HAT under both definitions (although, according to the latter, the reverse reaction is not HAT). Costentin, C., Evans, D. H., Robert, M., Savéant, J.-M., and Singh, P. S. J. Am.
