✦ Synopsis

A novel method for the kinetic study of a chemical reaction, HeI photoelectron spectroscopy (PES), is introduced. The prerequisites for the determination of the kinetic parameters of a chemical reaction using the PES method are: (1) there is a nonoverlapping band in the PE spectra of the reactant and the product; (2) the reaction course can be controlled by changing the temperature of the reaction system. For the isomerisation reaction CH3NC ~ CHaCN, the parameters obtained by the PES method are in agreement with previous results, indicating that PES is a reliable method to determine kinetic parameters of a chemical reaction. The relative photoionization cross-sections of the bands used for the sample studied are obtained from the value of the intercept in the kinetic equations.

The reactions (1) ( 2 ) have been studied competitively over the range of 2%182'C by photolysis of mixtures of C12 + C2F5I + CH4. We obtain log k l / k 2 = (0.96 f 0.06) + (1210 f 440)/0 where 0 = 2.303RT J/mol. The use of published data on reaction (2) leads to log (kl(cms/mol sec) = (13.96 f 0.2)
