Since the … Web13 sep. 2024 · Herein the non-TST behaviors of the rate constant were theoretically modelled by means of Kramers' theory and its extensions and by molecular dynamics (MD) simulations. The Z/E isomerization takes place in milliseconds or longer and so is not reachable by normal MD simulations.
WebOne of the most prominent advances was made by Kramers, who considered the problem of barrier crossing for a classical particle in a metastable potential subject to frictional forces and showed that the rate depends nonmonotonically on the friction.
