✦ Synopsis

Using 0.002 cm Ϫ1 resolution Fourier transform absorption spectra of an 17 O-enriched ozone sample, an extensive analysis of the 3 band together with a partial identification of the 1 band of the 17 O 16 O 17 O isotopomer of ozone has been performed for the first time. As for other C 2v -type ozone isotopomers [J.-M. Flaud and R. Bacis, Spectrochim. Acta, Part A 54, 3-16 (1998)], the (001) rotational levels are involved in a Coriolis-type resonance with the levels of the (100) vibrational state. The experimental rotational levels of the ( 001) and (100) vibrational states have been satisfactorily reproduced using a Hamiltonian matrix which takes into account the observed rovibrational resonances. In this way precise vibrational energies and rotational and coupling constants were deduced and the following band centers 0 ( 3 ) ϭ 1030.0946 cm Ϫ1 and 0 ( 1 ) ϭ 1086.7490 cm Ϫ1 were obtained for the 3 and 1 bands, respectively.
