Burkholder Title: 1,2-Dichlorohexafluoro-cyclobutane (1,2-c-C4F6Cl2, R-316c) a Potent Ozone Depleting Substance and Greenhouse Gas: Atmospheric Loss Processes, Lifetimes, and Ozone Depletion and Global Warming Potentials for the (E) and (Z) Stereoisomers Journal/Source: J. Phys. Chem. A, 117 (43), 11049-11065, (2013); DOI: 10.1021/jp407823k Data: diagram, table Energy/Wavelength range: 184.95 - 230 nm Resolution: Temperature: 214 - 296 K Temperature dependence: yes Pressure/Concentration: Phase: vapor pH: Comments: The atmospheric processing of (E)- and (Z)-1,2-dichlorohexafluoro-cyclobutane (1,2-c-C4F6Cl2, R-316c) was examined. UV absorption spectra were measured between 184.95 to 230 nm at temperatures between 214 and 296 K. The Cl atom quantum yield in the 193 nm photolysis of R-316c was measured to be 1.90 ± 0.27.
