Papadimitriou, M.R. McGillen, E.L. Fleming, C.H. Jackman, J.B. Burkholder Title: NF3: UV absorption spectrum temperature dependence and the atmospheric and climate forcing implications Journal/Source: Geophys. Res. Lett., 40 (2), 440-445, (2013); DOI: 10.1002/grl.50120 Data: table, diagram Energy/Wavelength range: 184.5 - 250 nm Resolution: Temperature: 212 K; 231 K; 253 K; 273 K; 296 K Temperature dependence: yes Pressure/Concentration: Phase: gas pH: Comments: The NF3 gas-phase UV absorption spectrum, sigma(lambda,T), was measured at 16 wavelengths between 184.95 and 250 nm at temperatures between 212 and 296 K. A significant spectrum temperature dependence was observed in the wavelength region most relevant to atmospheric photolysis (200-220 nm) with a decrease in sigma(210 nm,T) of ~45% between 296 and 212 K.
