Abstract
The 2 nu(1) + nu(2) + 2 nu(3) band of ozone, occurring in the 4780 cm( -1) region, has been observed for the first time, using a Fourier tran sform spectrometer, at 0.008 cm(-1) resolution and using a large path length pressure product. Assignments of vibration-rotational transitio ns have been made up to J = 48 and K-a = 9. As a few levels with K-a = 1 or 2 are perturbed, it has been necessary to take into account the Coriolis resonance between the (212) and (141) vibrational states. Wit h the effective Hamiltonian explicitly accounting for the interaction between these two states, the fit on 165 energy levels leads to the rm s deviation of 1.9 x 10(-3) cm(-1), which is near the experimental acc uracy. Line intensities of the 2 nu(1) + nu(2) + 2 nu(3) band have bee n measured and calculated. The set of spectroscopic parameters for int eracting bands, as well as transition moment constants, is given. A co mplete list of line positions and intensities, with a cutoff of 1 x 10 (-26) cm(-1)/molecule.cm(-2) at 296 K up to J = 65 and K-a = 15, has b een generated, which leads to the integrated band intensity S-nu(2 nu( 1) + nu(2) + 2 nu(3)) = (5.1 +/- 2.0) x 10(-23) cm(-1)/molecule.cm(-2) .
