Title: Temperature-dependent absorption cross-sections of CF3COCl, CF3COF, CH3COF, CCl3CHO and CF3COOH

Journal/Source: J. Photochem. Photobiol. A: Chem., 73 (1), 1-9, (1993); http://dx.doi.org/10.1016/1010-6030(93)80026-6


Data: diagram, table

Energy/Wavelength range: 200 - 360 nm 

Resolution: 1.2 nm (FWHM)

Comments: 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.
