Abstract: 

IR spectra for Cx F2x+1 CH CH2 (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 cm2 molecule−1 cm−1 were determined for Cx F2x+1 CH CH2 (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 Cx F2x+1 CH CH2 (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. Cx F2x+1 CH CH2 (x = 1, 2, 4, 6, 8) will not contribute significantly to radiative forcing of climate change.
