Résumé : About 400 absolute intensities have been measured for six bands(5 Σ-Σ and 1 Π-Σ bands) of 16O12C32S in the region of the ν1 + ν3 band near 3.4 μm. The majority of these bands exhibit weak to very strong Herman-Wallis behavior as a result of various anharmonic and l-type resonances between the upper levels involved. The individual line intensities were treated in two different ways. First, they were fitted to usual effective formulae, leading to the band strengths and Herman-Wallis factors. Second, the line intensities in the five Σ-Σ bands were fitted to a model taking explicitly into account the various anharmonic and I-type resonances between the upper levels. This treatment showed that these resonances quantitatively explain to a large extent the Herman-Wallis behavior observed. © 1995 Academic Press. All rights reserved.
