FIRST OBSERVATION AND ANALYSIS OF THE $3\nu_1$+$3\nu_3$ AND $2\nu_2$+$5\nu_3$ BANDS OF OZONE

Abstract

Using FTS and CW-CRDS spectrometer, high resolution spectra of ozone have been recorded with high sensitivity (respectively 8x10$^{-8}$ and 3x10$^{-10}$ cm$^{-1}$) in the range 6030-6130 cm$^{-1}$. Two A-type bands ($\Delta Ka=0$) have been observed. 391 transitions for the $3\nu_1$+$3\nu_3$ band and 280 transitions for the $2\nu_2$+$5\nu_3$ band have been assigned. In order to correctly reproduce the observations, it has been necessary to include three dark perturbing states. Transition moment parameters have been derived and a complete listing is calculated. We present spectra, Hamiltonian parameters, transition moment parameters as well as agreement between calculated and observed spectra in various spectral ranges.
