Atmospheric Chemistry of Perfluoroaldehydes (C x F2 x +1CHO) and Fluorotelomer Aldehydes (C x F2 x +1CH2CHO):  Quantification of the Important Role of Photolysis

Atmospheric Chemistry of Perfluoroaldehydes (C x F2 x +1CHO) and Fluorotelomer Aldehydes (C x F2 x +1CH2CHO):  Quantification of the Important Role of Photolysis

The UV absorption spectra of CF3CHO, C2F5CHO, C3F7CHO, C4F9CHO, CF3CH2CHO, and C6F13CH2CHO were recorded over the range 225−400 nm at 249−297 K. C x F2 x +1CHO and C x F2 x +1CH2CHO have broad absorption features centered at 300−310 and 290−300 nm, respectively. The strength of the absorption increa...

Zusammenfassung:The UV absorption spectra of CF3CHO, C2F5CHO, C3F7CHO, C4F9CHO, CF3CH2CHO, and C6F13CH2CHO were recorded over the range 225−400 nm at 249−297 K. C x F2 x +1CHO and C x F2 x +1CH2CHO have broad absorption features centered at 300−310 and 290−300 nm, respectively. The strength of the absorption increases with the size of the C x F2 x +1 group. There was no discernible (
