Abstract

The self-reaction of CF, CFH02 has been studied via time-resolved ultraviolet spectroscopy over the temperature range 21 1-372 K. The absorption spectrum of CF3CFHO2 extends from 190 to 275 nm with a maximum cross section of (5.2 0.3) X cm2 molecule-'at 213 nm. The UV absorbance of the reaction mixture decreases and shifts to the blue as the reaction progresses. This is consistent with the CF3CFH02 self-reaction producing CF3CFH0, the ...
