 Title: THE 2.5 $\mu m$ BANDS OF OZONE: LINE POSITIONS AND INTENSITIES Creators: Perrin, A.; Vasserot, A. M.; Flaud, J.- M.; Camy-Peyret, C.; Devi, V. Malathy; Smith, M. A. H.; Rinsland, C. P.; Barbe, A.; Bouazza, S.; Plateaux, J. J. Issue Date: 1991 Publisher: Ohio State University Abstract: A study of high-resolution ($0.010 cm^{-1}$) Fourier transform absorption spectra of $^{16}O_{3}$ in the region around 4020 $cm^{-1}$ has been performed. This study has resulted in the first extensive analysis of the $\nu_{1}+3\nu_{3}$ band of this molecule and the first observation of weaker lines from its $4\nu_{3}$ and $3\nu_{1}+ \nu_{2}$ bands. The rotational energy levels of the (103), (004), and (310) vibrational states of ozone have been satisfactorily reproduced using a Hamiltonian matrix which takes explicitly into account the classical Coriolis interaction of (103)$\leftrightarrow$(004) together with the unusual Coriolis-type (103)$\leftrightarrow$(310) and Fermi-type (310)$\leftrightarrow$(004) interactions. Under these conditions precise vibrational band centers and rotational and coupling constants were obtained. Also, over 130 line intensities were measured with an accuracy of 2-4\%. Analysis of these intensities has allowed the determination of the $\nu_{1}+3\nu_{3}$ and $3\nu_{1} + \nu_{2}$ vibrational transition moment constants. Finally, a complete list of line positions, intensities, and lower-state energies was generated for the $\nu_{1} + 3\nu_{3}$, $4\nu_{3}$ and $3\nu_{1} + \nu_{2}$ bands of $^{16}O_{3}$.""
