✦ Synopsis

The infrared spectrum of SCF 2 was recorded in the 1000 -1400 cm Ϫ1 region with a resolution of 2.5 ϫ 10 Ϫ3 cm Ϫ1 . The rotationally resolved 1 and 4 band systems were studied for the first time, and altogether 11 500 transitions were assigned. Both fundamentals are involved in strong anharmonic (Fermi) resonances. Effective centers (J ϭ K a ϭ K c ϭ 0) of the interacting bands are 1 1366.7117 cm Ϫ1 , 3 ϩ 2 5 1365.4257 cm Ϫ1 , 2 ϩ 3 1311.1491 cm Ϫ1 (a 1 species), and 4 1190.0839 cm -1 , 2 ϩ 5 1217.8191 cm Ϫ1 (b 1 species). The strong K a dependence of the 1 / 3 ϩ 2 5 level mixing enabled a numerical determination of the interaction constants while the other anharmonic interactions were accounted for by consideration of relative intensities. Deperturbed band centers, anharmonicity constants, and equilibrium and excited state rotational and centrifugal distortion constants were determined.

Using a Fourier transform spectrometer, we have recorded the spectra of ozone in the region of 4600 cm 01 , with a resolution of 0.008 cm 01 . The strongest absorption in this region is due to the n 1 / n 2 / 3n 3 band which is in Coriolis interaction with the n 2 / 4n 3 band. We have been able to a
