Discharge of Heavy Ions. Quasibarrierless and Quasiactivationless Processes
In several reactions, charge transfer is accompanied by a change in the coordinate of some heavy particle, for example, by a considerable stretching of some covalent bond. To begin with, let us consider the simplest case where the motion of particles, just like the motion of the solvent, is classical. As was described in Chapter 3, the activation in this case involves a gradual change both in the solvent coordinate q and the particle coordinate R. The activation energy will be determined by the distance from the minimum of the potential energy surface for the initial state to the saddle point on the line of intersection of this surface with the surface corresponding to the final state. This saddle point is characterized by the coordinates q*, R*, and the energy U*.
