Experimental studies of the ion yield of the reaction e-+ CF3Cl+CF,Cl-+CF3+ Cl-at low energies, E= O-8 eV and temperatures, T= 300-800 K, yield three effects: (A) A threshold peak, hardly noticeable at 300 K, becomes dominant for T> 700 K. (B) The first apparant (shape) resonance of the precursor io

β¦ Synopsis
The weak dissociative electron attachment to CHsCI below = 1 eV is very strongly dependent on the gas temperature; the rate constant for the process increases by 3 to 4 orders of magnitude when the temperature is increased from 300 to 750 K.

A classical theory of dissociative attachment (DA) is developed. The DA cross section 4,-. DA of a molecule in the initial vibrational state v is calculated. The model is applied to the negative ion formation in low energy electron scattering from CF3CI molecules. Temperature effects of the DA cross
Chlorinated hydrocarbons (CHCs) are some of the most difficult chemicals to incinerate. Regulatory requirements mandate destruction and removal efficiencies greater than 99.99%. High-temperature conditions needed for these destruction efficiencies also result in the formation of nitrogen oxides, as
