Abstract

IR spectra for C xF 2x+1CHCH 2 (x = 1, 2, 4, 6, 8) were recorded in 700 Torr of air, 298 ± 2 K. Integrated absorption cross sections (650-1800 cm -1) of (1.18 ± 0.06), (1.32 ± 0.07), (2.43 ± 0.12), (2.86 ± 0.14) and (3.32 ± 0.17) × 10 -16 cm 2 molecule -1 cm -1 were determined for C xF 2x+1CHCH 2 (x = 1, 2, 4, 6, 8), respectively. Radiative efficiencies of 0.159, 0.176, 0.338, 0.376, and 0.418 W m -2 ppb -1 were calculated for C xF 2x+1CHCH 2 (x = 1, 2, 4, 6, 8), respectively. The title compounds have short atmospheric lifetimes (approximately 7-8 days) and 100-year global warming potentials of ≤2. C xF 2x+1CHCH 2 (x = 1, 2, 4, 6, 8) will not contribute significantly to radiative forcing of climate change.
