Intensities and self-broadening coefficients of O3 in the 5 μm region

Abstract In order to derive intensities and self-broadening coefficients of ozone, numerous spectra have been recorded with the FTS of Reims ( S N = 800 , resolution 0.002 cm−1, corresponding to half of Doppler width). Great care has been taken to determine the amount of ozone. Least-squares fits, particularly suitable for O3, resulted in values for the intensities and self-broadening coefficients (αs) of 237 lines of ν1 + ν3, 2ν1, and 2ν3 bands. Wavenumbers and intensities are compared with data from the most recent analysis in this region. Values of αs are new. In addition, wavenumbers and intensities of a few lines of hot bands 2ν3 + ν1 − ν3 and ν1 + ν2 + ν3 − ν2 are compared with the compilation of Flaud, Camy-Peyret, Rinsland, Smith, and Malathy Devi.
