Infrared profiles and strength measurements have been obtained at a spectral resolution of 1.6 cm-1 for the absorption bands of CF2Cl2 (fluorocarbon12) from 900 to 1200 cm-1 at 296 and 200 K. A slight temperature dependence of the band strength seems to be observed for the &ngr;9+&ngr;9 combination band and for the (&ngr;9+&ngr;9) &ngr;e and (&ngr;1) &ngr;9 band systems. The low-temperature band profiles become narrower and the 0 branches stronger than they are at room temperatures. In particular, for the &ngr;e band, which is important for atmospheric sensing, the absorption coefficient shows an enhancement of 30% between 296 and 200 K at the peaks of the Q branch. These room temperature and low-temperature data may be useful for greenhouse calculations. |
