Thermal infrared absorption coefficients of CFC-12 at atmospheric conditions

Abstract Spectral absorption coefficients k v (cm -1 atm -1 ) have been measured in the 9 and 11 μm bands of CFC-12 (CF 2 Cl 2 ) using a high-resolution Fourier transform spectrometer. Temperature and total (broadening) pressure have been varied to obtain results at conditions representative of tropospheric and stratospheric layers of the atmosphere. The measured absolute intensities (in units of 10 -17 cm.molecule -1 ) of the 9 and 11 μm bands are 7.595 ±0.070 and 5.750 ±0.068, respectively.
