The literature concerning the ''greenhouse'' warming potentials of chlorofluorocarbons F-11, F-12, F-22, F-113, F-114, F-134a, and F-142b is reviewed. Additionally, infrared intensities are reported for each of the fundamental absorption bands of F-113 (CF2ClCFCl2) and F-114 (CF2ClCF2Cl) in the region between 8 and 20 μm. The measurements were made with a Fourier transform infrared spectrometer operated at 0.04 cm-1 apodized resolution. The total intensities measured for this region were 4905 cm-2 atm-1 for F-113 and 6064 cm-2 atm-1 for F-114, compared to a total intensity of 3404 cm-2 atm-1 for F-12 (CF2Cl2) in the same region. On the basis of these infrared intensities and the atmospheric lifetimes of F-113 and of F-114 relative to F-12, and on a per unit mass basis, F-113 and F-114 are about 0.8 and 1.9 times as effective, as F-12 in the ''greenhouse'' warming of the Earth. ¿ American Geophysical Union 1988
