 Title: FORMATION OF $O^{-}$ IONS IN THE MULTIPHOTON EXCITATION OF NO Creators: Ono, Y.; Hardwick, J. L.; Moseley, J. T. Issue Date: 1987 Publisher: Ohio State University Abstract: Formation of the $O^{-}$ anion in the gas phase has been observed following the multiphoton excitation of nitric oxide at low presssure. By examining both the the multiphoton lonization spectrum and the formation of $O^{-}$ ions from this molecule as a function of laser frequency, we are able to identify dissociative attachment of photoelectrons to the $A^{2}\Sigma^{+}$ electronic state of nitric oxide as the mechanism responsible for formation of negative ions.
