The N 1s partial photoionization cross sections of nitric oxide leading to the 3π and 1π ionic states were measured in the shape resonance region. Tentative assignments for the twin local maxima and the relative strengths of the exchange interactions in the σ * shape resonance region were presented. The partial cross sections leading to the 3π and 1π ionic states showed only one σ* shape resonance enhancement in the same photon energy. The results show that the relative intensities of the exchange interactions among the three open shells vary from valence to core photoionization.
