PCET proton-coupled electron experimentation

Theoretical treatments of PCET reactions typically have equation (1.2) as a conceptual starting point. In Hammes-Schiffer s multistate continuum theory for PCET, the pre-exponential factor includes both electronic coupling and vibrational overlaps, and the rate is a sum over initial and final vibrational states integrated over a range of proton-donor acceptor distances. This theory has been elegantly applied to understand the intimate details of a variety of PCET reactions, but many of its parameters are essentially unattainable experimentally.
