DOES THE STRUCTURE OF AN OSCILLATING CHEMICAL-SYSTEM OSCILLATE

The mesoscopic description of a system with chemical reactions predict s that if the detailed balance condition is not satisfied then spatial correlations between concentrations of reactants may appear. In this paper we use the molecular dynamics technique for reactive hard sphere s in order to obtain correlation functions for fluctuations in concent rations of the reactant for a model of an oscillating chemical system. It is shown that these functions depend on time and therefore the loc al structure of the system oscillates. A comparison between a theory b ased on the master equation and results of simulations is presented.
