Abstract

An important distinction between explicit and interpolated surfaces have been reviewed focusing on the transformations occurring in the lower range of energies, the abstraction reaction and the inversion exchange reaction. The H+CH₄ reaction and its isotopic variants have represented a target against which to test kinetics and dynamics theories and potential energy surface (PES) for polyatomic reactions. The review outlined the general description of the CH₅ surface and describes possible reaction mechanisms, presents available experimental data for reactive system and methods of constructing potential energy surfaces, investigates PES with a special focus the methods for the CH₅ system, and presents results of various theoretical investigations. As a conclusion, the quest for an accurate CH₅ PES is achieving success due to similarity in features of accurate PES.
