ABSORPTION PARAMETERS OF VERY DENSE MOLECULAR-SPECTRA FOR THE HITRAN COMPILATION

Cross sections for the heavy molecules CFC-11, CFC-12, CFC-13, CFC-14, CFC-22, CFC-1 13, CFC-1 14, CFC-115, CCl4, ClONO2, N2O5, HNO4, and HNO3 are included on the HITRAN 91 database. For many of these species, the cross sections vary by a factor of two between room temperature and temperatures near 210 K. The chemical importance of the heavy molecules, the quantitative accuracy of the HITRAN 91 cross sections, and the need for additional spectroscopic quantification are discussed.
