New results on the competition between autoionization and predissociation in the high Rydberg states of nitric oxide are presented. These results provide insight into the earlier work of Park {ital et al.} [Phys. Rev. Lett. {bold 76}, 1591 (1996)] that shows evidence for substantial mixing between Rydberg series and ionization continua with even and odd orbital angular momenta (l). New data based on fluorescence-dip spectroscopy, detection of neutral predissociation products, and photoelectron spectroscopy suggest that the A{sup {prime}}{sup 2}{Sigma}{sup +} and I{sup 2}{Sigma}{sup +} dissociative valence states play an important role in this l mixing. Zeeman splittings observed in a magnetic bottle electron spectrometer also result in an improvement in the assignment of these high Rydberg states. {copyright} {ital 1998 American Institute of Physics.}
