 Title: ABSOLUTE ABSORPTION OF OZONE IN THE MID-INFRARED Creators: Pickett, H. M.; Peterson, D. B.; Margolis, J. S. Issue Date: 1992 Publisher: Ohio State University Abstract: A number of spectroscopic investigators have measured ozone absolute intensities in different spectral regions. The mid-infrared frequencies have been studied by two $techniques ^{1,2}$. We report here the results of a distinctly different determination of the absorption cross section using a Bruker HR 120 Fourier transform spectrometer in the mid-infrared region. In this study, the infrared and ultraviolet, absorption of ozone were measured simultaneously using selected infrared lines of the $\nu_{3}$ band and the ultraviolet 253.7 nm Hg line. The accuracy of our absolute infrared intensity measurements are comparable to the 1 \% spread in the ultraviolet absorption measurements at 253.7 $nm^{3}$. Description: $^{1}$ C. Secroun, A.
