Dynamic Potential Barrier Effects in Hydrogen Tunneling in Trans-cis Isomerizations

Abstract

Most treatments of barrier tunneling make use of simplifying assumptions, such as one-dimensional paths. As chemists, we are often interested in processes that occur in polyatomic molecules, thus the tunneling processes of interest are often multi-dimensional. Makri and Miller have presented a method for treating tunneling in multi-dimensional systems semiclassically. However, it is often necessary and appropriate to calculate tunneling corrections by assuming that it occurs along some special 'tunneling direction', for example, along a normal mode direction
