The high-resolution photoabsorption spectrum of hexafluoropropene is reported in the wavelength range 115-320 nm (10.8-3.9 eV). Assignments are proposed for the features observed. The photolysis rate and lifetime of the molecule in the atmosphere are modelled as a function of altitude and compared with previous calculations made considering hexafluoropropene reactions with OH radicals.
