Detailed infrared spectroscopic studies of the photo-dissociation at 266 nm of C1NO2 trapped in argon matrices with subsequent experiments conducted with a xenon lamp at λ > 360 nm are reported. Formation of cis and trans C1ONO in equilibrium with C1NO2 is observed after irradiation at 266 nm. λ > 360 nm the transformation of trans C1ONO into cis C1ONO occurs. On prolonged photolysis at 266 nm, C1ONO dissociates into C1ON and O(1D) atom and into C10 + NO as evidenced in reactive matrices (solid oxygen and nitrogen).

The photolysis of ClONO2 has been studied at 254 nm.The production of NO3, NO2, and ClONO and the removal of ClONO2 have been obseved directly, and the yield of O(3P) has been inferred from the production of O3.The production of Cl and NO3 was found to be the dominant photolysis pathway.For ClONO2 concentrations of 5*1013 molecules cm-3, the values determined for the quantum yields for the removal of ClONO2, -ψClONO2, and the production of NO3, ψNO3, were 0.99+/-0.1 and 1.04+/-0.04, respectively.However, these yields appear to be dependent on the ClONO2 concentration and decrease as ClONO2 concentration increases.For ClONO2 concentrations in the range (3-8)*1014 molecules cm-3, the yields, obtained for the formation of O, NO2, and ClONO, are ψO=0.24, ψNO2=0.25, and ψClONO0.2.No evidence was found for a significant production of NO.The observed behavior may be explained by the production of a long-lived excited state of ClONO2.The results are discussed in relation to the stratospheric behavior of ClONO2.
