The unified treatment in this book explains why chemical reactions and other rare events, while having many common theoretical foundations, often require very different computational modeling strategies.

The Transition State Theory (TST) describes the reaction rates of rare events like
elemental chemical reactions (e.g. catalytic reaction of hydrogen and oxygen on
the surface of fuel cell electrodes) and diffusion processes in solid states (e.g.
oxygen ion diffusion in YSZ). It describes these processes on basis of a quasi-
equilibrium between the reactant species and the transition-state species by
assuming that the density of the Figure 4.1.: Schematic view of the 3N
dimensional phase ...

The rate of change of the atomic charge distribution along the reaction coordinate
was found to have a major effect on the dynamics. In the region of the barrier the
reaction was found to be characterized by nonadiabatic solvation, in which
solvent configurations are frozen and fail to maintain a rapid adiabatic
equilibrium with the solute. These and other factors controlling the dynamics
were revealed by the trajectory calculations. In later rare-event calculations of the
same reaction in ...

One of the reasons is that for many reactions, the passage through a reaction
channel is a rare event on the time scale of the fastest nuclear motions (vibrations
). In other words, the molecule is trapped most of the time in the valleys of the
potential energy surface. On the other hand, much is known how the shape of the
potential energy landscape affects reaction rates: this connection is made by
transition state theory. A transition state is the highest point on a minimum energy
path ...

EXAMPLE: SIMPLE REACTIONS IN SOLUTION By using the rare-event method
one may simulate reactions in solution and include the motions of the reacting
