Electron attachment processes in halomethanes

Abstract

We have investigated thermal electron capture processes in the mixtures of halomethanes and carbon dioxide (in excess) using the electron swarm method. We have found that except the very slow second order reactions (single collision) there occur processes involving homo-(RX)2 or heterogeniouos (RX·CO2) van der Waals complexes (multi-body pressure dependent processes) which are at least a few times faster at atmospheric pressures. The mechanism and the kinetics of some of these processes are presented.
