Hydrodynamic interaction effects on isomerization rates in chain molecules@fa@f)

摘要

The influence of hydrodynamic interaction effects on isomerization rates in chain molecules in solution is studied for a simple model. Attention is focused on the many particle reaction coordinate by which isomerization proceeds. It is found that the rate can be either enhanced or reduced by hydrodynamic interaction effects, depending on activation barrier and conformational properties. In the nonhyphen;Markovian regime, particle friction and hydrodynamics interaction effects on the rate are diminished, and the transition state theory limit is approached.
