SINOPSIS

Properties of the models of physical-chemical processes of dissociation and exchange reactions involving vibrationally excited molecules in the level description are an object of the investigation. The work is aimed at study and classification of the known and new models according to the principle of their information software and the complexity of their implementation with subsequent recommendations for practical use in applied problems. The main methodology of performing this work is the use of the principles of information and mathematical simulation. The result of the work done is a structured description of eight models of dissociation and exchange processes in the level description. In the process of testing the models and of conducting computational experiments some a priori unknown properties of the models and relationships between objective functions of different models are obtained. This has allowed one to substantially simplify the conditions for use of these models.
