Infrared absorption cross sections for carbon tetrachloride are reported over the range 730 to 825 cm-1 at four different temperatures (298, 273, 248, and 223 K). The absorption cross sections were measured using Fourier transform spectroscopy at a spectral resolution of 0.05 cm-1. The integrated band intensity for this spectral region was found to be (5.75¿0.30)¿10-17 cm2 molecule-1 cm-1, independent of temperature. The absorption cross sections were found to be essentially independent of spectral resolution (between 0.05 and 0.25 cm-1) and foreign gas pressure (0--1 atm at 298 K, 0--200 torr at 223 K), although changes of about 5 to 10% were noted in the structured regions of the spectrum. Our measured band intensity appears to be about 15% higher than recently published data. These differences are discussed in terms of their effect on previously reported stratospheric CCl4 altitude profiles. ¿ American Geophysical Union 1992 |
