Abstract :
More than 5050 rovibrational transitions were assigned in the very sensitive CW-CRDS 18O3 spectra in the 5900–7000 cm−1 range leading to the first determination of 14 new vibrational band centres. Three bands correspond to the highest ozone states observed so far under high resolution. The good agreement between predicted and observed centres (rms deviation of 1.1 cm−1) confirms the accuracy of the potential function previously determined from 16O3 data. At this energy range situated ∼20% below the dissociation energy, the small changes of masses associated with the 16O3 → 18O3 homogeneous isotopic substitution result in irregular isotopic shifts.
