Radiative electron-attachment spectra of O3and SO2

Abstract
Several aspects of radiative electron-attachment processes are discussed and the corresponding photon energy spectra computed for O3 and SO2. In both cases the vibrational stretching mode is significantly excited. The calculated electron attachment spectrum of SO2 is compared with the laser photo-detachment spectrum of SO2 -. The computed electron affinities and changes in geometry between natural and negative ion are in good agreement with the experimental data.
