A model is proposed for coupled hydrogen-electron transfer reactions in condensed phase in the presence of a promoting vibration. The model is an extension of an earlier model, which modulates the potential the hydrogen atom experiences as it is transferred. Large kinetic isotope effects (KIE) were found when the hydrogen is substituted with deutrium. The results show that a large, temperature-independent KIE is compatible with a tunneling reaction assisted by a promoting vibration.
