The high resolution CW-CRDS infrared spectra of ozone have been recorded in the 5970-6200 cm-1 spectral range. The high sensitivity allow to observe very weak lines. In this region, only two A type bands centred at 6063 and 6124 cm-1 were previously analysed. Here, thanks to the record of new spectra, we largely extend the range of their observed quantum numbers, and, first of all, we observe three B type bands: 2
1 +3
2 +2
3 (138 transitions), 5
1 +
2 (16 transitions), and
1+2
2 + 4
3 (499 transitions). It is necessary to include 6 vibrational levels in the Hamiltonian model, accounting of many resonances to correctly (r.m.s=6x 10-3 cm-1 reproduce the observed positions.
In addition, transition moment are fitted. Finally, more than 95% of all experimentally observed lines are assigned and are satisfactorily reproduced, accounting of the difficulty of analyses of levels not far from the dissociation.
