The ultraviolet absorption spectrum of gas phase CF3OONO2 has been measured over the wavelength range 200–340nm at 233–300 K. Absorption cross-sections at wavelengths of 290–340nm were found to increase significantly with increasing temperature. The UV spectra of CF3C(O)Cl and CF3C(O)F were measured and were consistent with previous work [Rattigan et al., 1993. Temperature-dependent absorption cross-sections of CF3COCl, CF3COF, CH3COF, CCl3CHO and CF3COOH. Journal of Photochemistry and Photobiology A: Chemistry 73, 1–9]. Implications for the atmospheric chemistry of CF3OONO2 are discussed3OONO2 has been measured over the wavelength range 200–340nm at 233–300 K.
