Abstract
Using $0.002 cm^{-1}$ Fourier transform absorption spectra of $^{17}O-$ enriched sample of ozone, an extensive analysis of the $\nu_{3}$ band together with a partial identification of the $\nu_{1}$ band of the $^{17}O^{17}O^{16}O$ and $^{17}O^{16}O^{17}O$ isotopic species of ozone has been performed in the $10 \mu m$ region. The experimental rotational levels of the (001) and (100) vibrational states could be reproduced using an Hamiltonian matrix which takes into account the expected rovibrational resonances. As for the other $C_{s}$ -type ozone $isotopomers^{a}$, the (001) rotational levels of $^{17}O^{17}O^{16}O$ are involved in both Coriolis and Fermi type resonances with the levels from the (100) vibrational state. On the other hand, for the $^{17}O^{16}O^{17}O C_{2}v$ -type isotopomer, only C-type Coriolis resonances have to be considered. Using an Hamiltonian matrix which takes into account these resonances for the (001)-(100) off- diagonal blocks, and an A-type Watson operator for the diagonal blocks, precise vibrational energies and rotational and coupling constants are deduced.
