The mechanism and kinetics of electron capture by haloethanes

Języki publikacji

Abstrakty

This review is a continuation of our effort to measure systematically the rate constants for thermal electron capture by bromo-, chloro- and fluoroethans in the mixtures with carbon dioxide using the electron swarm method. All the experimental data show that only two-body reactions occur. The linear dependence of the rate constants (log k) on the electron polarizabilities of the attaching center has been found. Theoretical analysis using PM3 semiempirical method with a commercial HyperChem program were performed and the structure of neutral molecule and its negative ion has been calculated. These results have been compared with the molecular characteristics and thermal electron capture rate constants.
