Francisco, I.H. Williams Title: A re-examination of the infrared and ultraviolet spectroscopy of trifluoroacetyl fluoride and trifluoroacetyl chloride: An experimental and theoretical study Journal/Source: Spectrochim. Acta Part A: Molecular Spectroscopy, 48, 1115-1126, (1992); doi:10.1016/0584-8539(92)80121-C Data: Energy/Wavelength range: Resolution: Temperature: Temperature dependence: Pressure/Concentration: Phase: pH: Comments: The UV absorption spectra of CF3C(O)F and CF3C(O)Cl show a structureless continuum with a maximum at 21Onm (sigma(max)=3.20±0.02 × 10-20 cm2 molecule-1) and 255 nm (sigma(max)=7.66±0.26 × 10-20 cm2 molecule-1), respectively.
