Goldfarb, A.-M. Schmoltner, M.K. Gilles, J.B. Burkholder, A.R. Ravishankara Title: Photodissociation of ClONO2: 1. Atomic Resonance Fluorescence Measurements of Product Quantum Yields Journal/Source: J. Phys. Chem. A, 101 (36), 6658 -6666, (1997); jp970818f S1089-5639(97)00818-9 Data: Energy/Wavelength range: 193.2, 222.0, 248.25, and 308.15 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: 40-100 Torr (He and N2) Phase: gas pH: Comments: The quantum yields for the production of Cl, O, and ClO in the photolysis of ClONO2, measured by detecting Cl and O atoms by atomic resonance fluorescence, are reported. The quantum yields for Cl in the 193.2, 222.0, 248.25, and 308.15 nm photolysis of ClONO2 were 0.53 ± 0.10, 0.46 ± 0.10, 0.41 ± 0.13, and 0.64 ± 0.20, respectively. The yields for O atoms at these wavelengths were, respectively, 0.37 ± 0.08, 0.17 ± 0.05, <0.10, and <0.05. The obtained quantum yields for ClO were 0.29 ± 0.20, 0.64 ± 0.20, 0.39 ± 0.19, and 0.37 ± 0.19, at 193.2, 222.0, 248.25, and 308.15 nm, respectively.
