Abstract

We present a study of multimode effects in dissociative electron attachment to CF3Cl molecules using a
time-independent version of the local complex potential theory. Symmetric stretch C-Cl vibrations 3 and
symmetric deformation or so-called umbrella vibrations 2 are included. The neutral and anion potential
energy surfaces are calculated using the second-order Møller-Plesset perturbation theory with an empirical
adjustment of the vertical attachment energy. The final-state vibrational distribution in the CF32 fragment is
dominated by the ny=2 state. We also find an increase in the total cross section as compared with the
one-dimensional calculations. This is explained by an increase in the anion survival probability.
