Rattigan, O. Wild, R.L. Jones, R.A. Cox Title: Temperature-dependent absorption cross-sections of CF3COCl, CF3COF, CH3COF, CCl3CHO and CF3COOH Journal/Source: J. Photochem. Photobiol. A: Chem., 73, 1-9, (1993); doi:10.1016/1010-6030(93)80026-6 Data: table, diagram Energy/Wavelength range: 200 - 280 nm Resolution: 1.2 nm (FWHM) Temperature: 296 K Temperature dependence: yes Pressure/Concentration: Phase: pH: Comments: Absorption cross-sections for CF3COCl, CF3COF, CH3COF, CCl3CHO and CF3COOH have been measured in the wavelength region 200-360 nm. Absorption over most of the wavelength range showed a distinct temperature dependence, with a significant decline in the cross-section in the long wavelength tail with decreasing temperature.
