Use of the Monte Carlo method in solution of gas kinetics problems

Among the possible applications of Monte Carlo methods (computer mathematics, neutron transfer theory, aerodynamics of a rarified gas, kinetic theory of gases), chemical kinetics is one of the newest and most promising fields. In recent years interest has grown sharply in the study of reactions at the molecular level, i.e., study of the elementary acts of various processes and the related nonequilibrium energy distributions over translational and internal degrees of freedom. Monte Carlo methods appear intended for study of these phenomena. Hence the goal of this overview, aside from relating present attainments in the area, is to call to the attention of people occupied with the study of chemical kinetics the possibilities of Monte Carlo methods.
