This work continues the systematic study of the rovibrational spectra of ozone in the infrared, newly using the high sensitivity CW-cavity ring down spectroscopy ( alphamin ~ 3× 10-10 cm-1) . Here, we observe two new A type bands, where the main contributers are nu1+3 nu2+3 nu3 and 4 nu1+ nu2+ nu3 centered at 5919.154 and 5947.071 cm-1 respectively. We report for each of them the Hamiltonian parameters, the transition moment parameters, the range of observed quantum numbers, the statistics for line position and intensities, the list of "observed energy levels", with the comparison with their calculations and we show various examples of agreements between observed and calculated spectra. In addition, a comparison between observed and predicted band center \footnoteVl.G. Tyuterev, S.A. Tashkun, H. Seghir, A.
