Orlando, J.B. Burkholder, S.A. McKeen, A.R. Ravishankara Title: Atmospheric Fate of Several Hydrofluoroethanes and Hydrochloroethanes: 2. UV Absorption Cross Sections and Atmospheric Lifetimes Journal/Source: J. Geophys. Res., 96, 5013-5023, (1991); DOI: 10.1029/90JD02734 Data: table, diagram Energy/Wavelength range: 170 - 248 nm Resolution: Temperature: 203 K; 223 K; 243 K; 263 K; 295 K Temperature dependence: yes Pressure/Concentration: Phase: vapor pH: Comments: The temperature dependent UV absorption cross-sections of the hydrochlorofluoroethanes CF3CHFCl, CH3CF2Cl, and CF3CHCl2 are reported. The UV absorption cross-sections were measured over the temperature range 203 to 295 K and the wavelength range 190 to 230 nm. The hydrofluorocarbons CH3CF2H and CF3CH2F were also studied at 295 K and upper limits for their UV absorption cross-sections over the wavelength range 190 to 230 nm were obtained.
