Taketani, K. Takahashi, Y. Matsumi Title: Quantum Yields for Cl(2Pj) Atom Formation from the Photolysis of Chlorofluorocarbons and Chlorinated Hydrocarbons at 193.3 nm Journal/Source: J. Phys. Chem. A, 109 (12), 2855-2860, (2005); DOI: 10.1021/jp044218+ Data: Energy/Wavelength range: 193.3 nm Resolution: Temperature: 295 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The quantum yields for total Cl-atom formation in the 193.3 nm photolysis at 295 ± 2 K have been determined to be 1.03 ± 0.09, 1.01 ± 0.08, 1.03 ± 0.08, 1.03 ± 0.10, 1.41 ± 0.14, 1.02 ± 0.08, and 0.98 ± 0.08 for CF2Cl2, CFCl3, CH2Cl2, CHCl3, CCl4, CHFCl2, and CCl3CF3, respectively. The quantum yields for total Cl-atom formation in the 193.3 nm photolysis of CHBr2Cl and CHBrClCF3 are 0.27 ± 0.02 and 0.28 ± 0.02, respectively.
