Radiative electron-attachment spectra of O₃ and SO₂ a theoretical investigation

Institut fur Theoretische Chemie der Technischen Universitat Munchen, D-8000 Munchen, Germany 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 S02 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.
