✦ Synopsis

Using a high-pressure (\times) path length sample of ozone it has been possible to record at high resolution ( (0.006 \mathrm{~cm}^{-1}) ) the (3-\mu \mathrm{m}) absorption region of this molecule. A thorough analysis of the spectra has been performed allowing one to assign for the first time the (3 \nu_{1}) band of ({ }^{16} \mathrm{O}{3}). Also, during the course of the analysis it became clear that, in this spectral region, another band almost as strong as (3 \nu{1}) was absorbing: it is the (\nu_{1}+3 \nu_{3}-\nu_{2}) hot band. The ((300)) rotational levels were reproduced together with the ((003),(102)), and (201) ones [J. Mol. Spectrosc. 141, 134-144 ( 1990 )] using a Hamiltonian matrix which takes explicitly into account the Darling-Dennison and the Coriolis interaction terms affecting the levels. The band centers (\nu_{0}\left(3 \nu_{3}\right)=3046.0878), (\nu_{0}\left(\nu_{1}+2 \nu_{3}\right)=3083.7030, \nu_{0}\left(2 \nu_{1}+\nu_{3}\right)=3186.4110), and (\nu_{0}\left(3 \nu_{1}\right)=3289.9297 \mathrm{~cm}^{-1}) were derived as well as precise rotational and coupling constants. Line intensities were also measured for (3 v_{1}) as well as for (\nu_{1}+3 \nu_{3}-\nu_{2}) and were reproduced with suitable transition moment operators. Finally a complete line list of the bands of ({ }^{16} \mathrm{O}_{3}) absorbing around (3 \mu \mathrm{m}) has been generated. C 1993 Academic Press. Inc.
