OXIDES AND PEROXIDES
This group ranges from the most stable of compounds--CO2--to some of the most reactive, including ozone.
The carbon dioxide spectrum in QASoft is a composite spectrum created by splicing together bands from several spectra. The strong bands are taken from a spectrum of only about 100 ppm-meters of CO2, while the weak bands are taken from spectra of many thousands of ppm-meters. The spectra were scaled up and down so that they matched at the places where they were joined. The resulting "master" spectrum has an extremely low noise level and can be used over wide ranges of concentration.
Ozone is easy enough to create with an electric discharge or with ultraviolet light, but it is a difficult compound to measure. The ozone absorption coefficients have been measured and re-measured over the years because of the importance of knowing how much ozone exists in the photochemical smog. In the present work the ozone measurement is based on the absorption coefficients published in the article "Infrared Absorptivity of the 9.6 Micron Ozone Band as a Function of Spectral Resolution and Abundance" by J. M. McAfee, E. R. Stephens, D. Fitz, and J. N. Pitts, Jr., J. Quant. Spectrosc. Radiat. Transfer, 16, (1976), pp. 829-837. See SPECTRA, chapter F.
