Abstract
The $\\nu_{2} +3\\nu_{3}$ band of 16O3 has been analyzed based on room temperature absorption spectra of ozone recorded at a resolution of $0.01 cm^{-1}$ with the McMath Fourier transform spectrometer at the National Solar Observatory on Kitt Peak. An extensive and accurate set of rotational energy levels of the (013) vibrational state has been determined. These experimental levels were very satisfactorily reproduced using a Hamiltonian which takes into account the Coriolis type resonance with the levels of the non-observed (112) vibrational state. Moreover, line intensities of the $\\nu_{2}+3\\nu_{2}$ band measured with a relative accuracy of about 8\\% were least squares fitted lending to the determination of the transition moment constants of this band. Finally, using these constants, a complete listing of line positions, intensities, and lower energy levels was generated
