Configuration interaction calculations of the satellite peaks observed in the core and valence photoelectron spectra of N2

Configuration interaction calculations are used to interpret satellite peaks observed in the X-ray and He (II) photoelectron spectra of N₂. Using a basis containing diffuse atomic functions, the X-ray peaks are assigned to states involving transitions to valence and Rydberg type orbitals. The three satellites in the He (II) spectrum are correlated with states involving occupancy of the 1π_g and 4σ_g molecular orbitals.
