Application of the Monte Carlo Method to Modeling Kinetic Processes of Polyatomic Molecules and Clusters: II. Kinetics of Unimolecular Reactions of Polyatomic Molecules

The method for statistical modeling of the kinetics of unimolecular decomposition of polyatomic molecules based on the construction of nonequilibrium functions of the distribution over the energies of the vibrational excitation of molecules is developed. The rate constants for the two-channel decomposition of a model molecule depending on temperature and pressure are reported. The relaxation characteristics for the dissociation of the model molecule are determined.
