Dissociative electron attachment and vibrational excitation of CF3Cl: Effect of two vibrational modes revisited

Tarana, M.; Houfek, K.; Horáček, J.; Fabrikant, I. I.

We present a study of dissociative electron attachment and vibrational excitation processes in electron collisions
with the CF3Cl molecule. The calculations are based on the two-dimensional nuclear dynamics including the C-Cl
symmetric stretch coordinate and the CF3 symmetric deformation (umbrella) coordinate. The complex potential
energy surfaces are calculated using the ab initio R-matrix method. The results for dissociative attachment
and vibrational excitation of the umbrella mode agree quite well with experiment whereas the cross section
for excitation of the C-Cl symmetric stretch vibrations is about a factor-of-three too low in comparison with
experimental data.
