β¦ Synopsis
A dynamical theory for the rate constant k of hydrogen atom and proton transfer reactions in solution is presented for the nonadiabatic limit, where reaction is dominated by tunneling. Coupling and splitting fluctuation effects arising from intramolecular vibrational and solvent fluctuations are included in the description. Limiting regime analytic results fork are presented for high and low temperature and for weak and strong salvation. Differences between proton and hydrogen atom transfers are indicated, as are the contrasts with electron transfer rates.
