KASSI, A. CAMPARGUE, Universite´ Grenoble 1/CNRS, UMR5588 LIPhy,Grenoble, F-38041, FranceThe very sensitive CW-Cavity Ring Down Spectra of 18O enriched ozone iso-topologues were recorded in the 5850 – 6920 cm−1 spectral range1. The ozonegeneration from two mixtures of 16O2 and18O2 leads to the production of the five18O enriched ozone isotopologues, in addition to 16O3. The contributions of the16O16O18O/16O18O16O and of the 16O18O18O/18O16O18O isotopomers were sepa-rated using two partial pressures of 16O2/18O2. Here we present the results of theanalysis of four rovibrational bands of the 16O18O18O isotopologue of CS symme-try: 7ν3, 2ν2+5ν3, 2ν1+2ν2+3ν3 and 2ν1+5ν3 centred at 5880, 6055, 6168, 6628cm−1, respectively. The initial assignment was performed using the band centres2and rotational constants derived from recent theoretical predictions from the molec-ular potential function3. For each band, the positions and intensities of the assignedtransitions were modelled using the effective operator approach. The effective Hamil-tonian model includes a number of dark state levels. For each band system, we willpresent the number of assigned transitions, the statistics of fits and some examples ofagreement between measured and simulated spectra.1doi:10.1016/j.jqsrt.2012.10.023, D.
