Results of calculations of the photoelectron spectra for single-photon pulsed-field ionization of the 1 pi orbital of the X (2) Pi (nu " = 0) ground state NO leading to the alpha (3) Sigma(+) (nu(+) = 0-2) excited ionic state are reported. Agreement between these calculated and recently measured spectra is very encouraging. Comparison of these spectra for ionization of the 1 pi level of NO (X (2) Pi) With those for the 2 pi orbital reveal significantly different spectral profiles and underlying dynamics for these two cases.
