Photoionization and photodissociation of nitric oxide in the range 9–35 eV

Abstract
Photoionization and photodissociation of NO has been studied using 9–35 eV synchrotron light and detection of fluorescence as well as of mass selected NO+, N+, O+, and O− ions. Rydberg series converging to all known states in NO+ below 24 eV have been analyzed and classified and several of them are found to be predissociated by various NO+ states as well as by NO ion pair states. The complex structure in the 950–1200 Å excitation region is suggested to originate from interaction between a ‘‘new’’ NO valence state at T0=77 470 cm−1 and high vibrational levels of Rydberg series converging to the NO+ ground state.
