A NOVEL METHOD FOR THE KINETIC-STUDY OF A CHEMICAL-REACTION - DETERMINATION OF THE KINETIC-PARAMETERS OF THE ISOMERIZATION REACTION OF METHYL ISOCYANIDE USING HEI PHOTOELECTRON-SPECTROSCOPY

A novel method for the kinetic study of a chemical reaction, HeI photo electron spectroscopy (PES), is introduced. The prerequisites for the determination of the kinetic parameters of a chemical reaction using t he PES method are: (1) there is a nonoverlapping band in the PE spectr a of the reactant and the product; (2) the reaction course can be cont rolled by changing the temperature of the reaction system. For the iso merisation reaction CH3NC --> CH3CN, the parameters obtained by the PE S method are in agreement with previous results, indicating that PES i s a reliable method to determine kinetic parameters of a chemical reac tion. The relative photoionization cross-sections of the bands used fo r the sample studied are obtained from the value of the intercept in t he kinetic equations.
