A theoretical interpretation of the satellite peaks associated with core electron ionization of N2O

The satellite spectra associated with both oxygen and nitrogen 1s ionization of nitrous oxide are interpreted using configuration interaction calculations whose basis orbitals are the MO's of the corresponding core hole state, obtained by restricted Hartree—Fock calculations. The most intense peaks in the spectra are assigned to π → π transitions, and their intensities are correlated with the atomic character of the π MO's of N2O.
