science-softCon uv/vis+ photochemistry database; www.photochemistry.org; (C) science-softCon 2019 Substance: 1,1,1',1'-tetrafluorodimethyl ether Other names: (Difluoromethoxy)(difluoro)methane Formula: C2H2F4O; CHF2-O-CHF2 CAS-No.: 1691-17-4 Study: uv and ir spectra Authors: V.L. Orkin, E. Villenave, R.E. Huie, M.J. Kurylo Title: Atmospheric Lifetimes and Global Warming Potentials of Hydrofluoroethers: Reactivity toward OH, UV Spectra, and IR Absorption Cross Sections Journal/Source: J. Phys. Chem., A, 103, 9770-9779, (1999); DOI: 10.1021/jp991741t Data: table, diagram Energy/Wavelength range: 160 - 182 nm Resolution: 0.5 nm Temperature: 295 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: Infrared absorption cross sections of HFOC-134, HFOC-356mff, and HFOC-125 (CHF2-O-CF3) were measured at T = 295 K from 500 to 1600 cm-1 and the global warming potentials of the three compounds were estimated. Ultraviolet absorption spectra of the ethers were measured between 160 and 220 nm. Author to whom correspondence should be addressed: (e-mail address)
