Abstract

The trifluorovinyl radical (C2F3') is identified by using infrared spectroscopy. Real-time broadband infrared laser and diode infrared laser absorption spectra of the trifluorovinyl radical were measured. The radical was generated from UV laser photolysis of trifluoroiodoethene (C2F, I) at 248 nm in the gas phase. The observed vibrational frequencies and intensities [u,, 1290 (f5) cm-I, 106 (f39) km mol-I; and u3. 1225 (* 5) cm-I, ...
