ANALYSIS OF HIGH RESOLUTION INFRARED SPECTRA OF OZONE IN THE $4600 cm^{-1}$ REGION

Abstract

The spectra of ozone using high product $p \times \ell$ have been recorded with the Fourier Transform spectrometer of Reims, with a resolution of $0.008 cm^{-1}$, p = 40 Torr $O_{3}$, L = 36 m, in the $4 600 cm^{-1}$ region. This one corresponds mainly to the $\nu_{1} + \nu_{2} + 3\nu_{3}$ band. The analysis of this band is difficult due to the presence of the two very closed interacting bands $\nu_{2} + 4\nu_{3}$ and $3\nu_{1} + 2\nu_{2}$: Many transitions of these two weak bands have been observed, up to J = 50 for $\nu_{2} + 4\nu_{3}$ and one serie corresponding to K = 3 for $3\nu_{1} + \nu_{2}$. We have used an hamiltonian which takes explicitely account of Coriolis coupling between 113 and 014, 113 with 320 as well a Fermi resonance between 014 and 320. The set of parameters of these states, comparison $O^{bs} - C^{alc}$, as well as intensities are presented.
