LINE POSITIONS AND INTENSITIES OF THE 3-UPSILON(1)+UPSILON(3) BAND OFOZONE

Infrared spectra of O-16(3) have been recorded in the 4250 cm(-1) regi on with a Fourier transform spectrometer, at 0.008 cm(-1) resolution, using a White-type cell l = 36.16 m filled with 42.8 Torr O-3. This sp ectral region corresponds to the 3v(1) + v(3) band, which has never be en observed before. The assignment of this band has been performed up to J = 43 and K-a = 13. To correctly reproduce the obtained energy lev els of (301), it has been necessary to introduce the (230) dark state, interacting with (301) through Coriolis resonance. With the Hamiltoni an for these two vibrational states, the fit on the 282 energy levels results in the RMS = 1.8 x 10(-3) cm(-1), on the order of the experime ntal precision. Line intensities of the 3v(1) + v(3) are measured and calculated. We report here the set of molecular parameters and transit ion moment constants. A complete list of lire positions and intensitie s with the cutoff of 1 x 10(-26) cm(-1)/molecule . cm(-2) at 295 K up to J = 55 and K-a = 17 has been generated, covering the region 4170-42 65 cm(-1).
