✦ Synopsis

An analytic theory is presented for the thermally activated rate constant in systems which exhibit spatially dependent and timecorrelated friction along the reaction coordinate motion. The theory is valid over the entire range of damping strengths, including in the region of the Rramers turnover. It is compared to the results of computer simulations on a model nonlinear system and excellent agrccmcnt is obtained. The prcscnt work significantly gene&ii existing theories for the activated rate constant which arc based on the general&d Langevin equation for the reaction coordinate motion and spatially independent friction.
