Autoionization of valence and Rydberg states in NO over the 12.5-18 eV photon energy range was studied by vibrationally resolved photoelectron spectroscopy of the 2π orbital. Complex, oscillatory structure is observed in NO+ (2Π-1) X1ς+ partial cross sections, branching ratios, and photoelectron and anisotropy parameters due to autoionizing valence states and Rydberg states associated with the 1Π-1 and 5ς-1 channels. Autoionization of the 5ς->npΠς(upsilon'}=0), n=3-5 Rydberg states leading to the (5ς1) b3II state of NO+ produces very high vibrational levels of (2π-1) X1ς+. Autoionization of the 5ς-> 3pπ(upsilon'}=0) Rydberg state was characterized by resonance profiles of photoelectron cross sections and angular distributions.
