Interpretation of resonance states of the molecular negative perfluoropropylene ion

An algorithm for interpreting resonance states of molecular negative ions has been suggested. This algorithm, using quantum-chemical calculations, allows one to select vacant MO that can be excited in a series of resonances, the energy gap between which coincides with the difference between the corresponding ionization energies. The resonance states of the molecular negative perfluoropropylene ion at energies of electrons from 0.5 to 12.0 eV are formed according to the mechanism of electron-excited Feschbach resonance. Spectral parameters of these resonances have been established.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 9, pp. 1701–1704, September, 1995.
