Bottlenecks many-dimensional systems

Implicit in the application of reactive islands theory, or in the application of other models of reaction dynamics that make use of the properties of a reaction separatrix, is the idea that the chaotic phase space may be considered to be completely structureless (within the restrictions imposed by the homoclinic/heteroclinic tangling of the separatrix manifolds). However, the presence of internal bottlenecks within one or more isomers may cause this approximation to break down.2 io3-i05,iu Accurate procedures for developing corrections to account for internal bottlenecks in two-dimensional systems have been developed. - > > 2 Unfortunately, much progress remains to be made toward developing quantitative procedures for dealing with internal bottlenecks in many-dimensional systems.
