✦ Synopsis

The analysis of high-resolution spectra of 18 O 3 is reported here for the range 3100-5000 cm -1 . Eight sets of polyads, corresponding to eight newly observed bands and accounting for resonance perturbations with eight other "dark" states, are analyzed for the first time. These analyses lead to eight sets of spectroscopic parameters, band centers, and rotational and centrifugal distortion constants, as well as transition moment parameters. In addition, various resonances are studied and compared to the similar ones for 16 O 3 . This study allows us to check the work on 16 O 3 and to confirm that the accidentally strong high-order v = 8 anharmonic resonance for bands 5 ν 3 ↔ 3ν 1 + ν 2 + ν 3 was an exceptional case of the major isotopic species.

Using a Fourier transform spectrometer, we have recorded the spectra of the 18 O 3 species of ozone in the region 1300-3100 cm -1 , with a resolution of 0.003 cm -1 . The large product pathlength × pressure enable us to record 18 bands, 14 for the first time. The analysis has been performed using ef
