Abstract

Thanks to the record ofnew FTS spectra of O₃ in the 4300 cm¹ region, the 122-000 band is now observed. Assignments of line transitions for following values of rotational quantum numbers J and K_a: 10 < J < 51 , K_a ≤ 8 were done. In the linelist about 443 transitions of v₁+2v₂+2v₃ band are presented. To correctly reproduce the obtained energy levels of (122) state, the very weak "dark state" (400) was introduced. A data reduction has been done using effective Hamiltonian for three interacting states {400, 122 023}, which are coupled through the usual Coriolis and high order rotational and vibrational resonances. The final fit on the 589 energy levels is quite satisfactory. The root mean square deviation between observed and calculated values is about O.0029cm^-1. The fit of line intensities allows us to derived transition moment parameters for 2v₂+3v₃ and v₁+2v₂+2v₃ bands.
