In this review, we identify several fundamental concepts and models that have been challenging to students and teachers: (1) the Marcus theory of electron transfer reactions; (2) the Landau–Zener model for diabatic transitions; (3) the concept of reaction path curvature as illustrated by the affine transformation; and (4) a progression of stochastic models: the Langevin equation, the Fokker–Planck equation, and Kramers’ theory of phase space diffusion as embodied in the Klein–Kramers equation.
The gravamen of the work is the connection between Kramers’ version of Transition State theory in the context of phase space diffusion. These classical concepts are then transferred to the realm of quantum chemistry, where we outline a program for tracking ensembles of time-dependent wave functions in analogy with their classical counterparts by means of a superoperator space and a Trace Algebra.
