Abstract

In this paper we present a theoretical framework for describing the role of solvent and vibrations on proton tunneling rates. Recent experiments indicate that excited-state proton transfer in ROH(NH₃)_n clusters (where ROH is 1-naphthol or phenol) occurs by a tunneling mechanism. Two previous models of proton tunneling are examined; one based on a solvent-independent bound- continuum potential and the other on a solvent-activated bound-bound potential. Here we extend the latter model to incorporate coupling of the proton to reactant and product vibrations. All three models are compared to experimental tunneling rates in clusters.
