Photofragmentation of nitryl chloride (CINO2) is reported in the ultraviolet (UV) (lambda = 240 nm and lambda = 308 nm) and in the vacuum ultraviolet (VUV) regime (55 nm less than or equal to lambda less than or equal to 110 nm, corresponding to the photon energy range 11.3 eV less than or equal to E less than or equal to 22.5 eV), where pulsed radiation is used to excite the neutral molecule in the gas phase. The neutral photolysis products that are formed upon UV photolysis are subsequently probed by photoionization mass spectrometry by using time-correlated tunable laser-produced plasma VUV radiation. UV-pump/VUV-probe experiments allow us to identify two primary photolysis channels at lambda = 308 nm: (i) Cl + NO2 and (ii) O + ClNO. Primary quantum yields for atomic product formation are deduced from photoionization experiments for both channels: gamma (308) nm(Cl) = 0.93 +/- 0.10, and gamma (308) nm(O) = 0.07 +/- 0.01. The yield of Cl formation (N(Cl)) is significantly reduced relative to that of O formation (N(O)) at lambda = 240 nm, corresponding to a N(Cl)/N(O) ratio of 1.44 +/- 0.15. The atomic oxygen is found to be formed in its P-3 ground state at both photolysis wavelengths. The present results are compared to earlier work, and atmospheric implications of the present results are briefly discussed. The tunable VUV Light source also allows us to perform photoionization mass spectrometry experiments on nitryl chloride without primary photolysis. These experiments yield the first ionization energy of ClNO2 as well as fragmentation thresholds of ClNO2+.
