A new apparatus for measuring rate constants and activation energies of thermal electron capture processes in the gas phase

Abstract

The new apparatus for investigation of kinetics of a thermal electron capture process and its temperature dependence with pulsed Townsend technique has been built. This method gives straightforward results on electron drift velocities in any mixture and allows calculating the rate constants for electron capture as well as activation energies of this process. The thermal electron capture rate constants and activation energies for CH 3CCl 3, CHCl 2CH 2Cl and CH 3CHClCH 2CH 3 have been determined.
