✦ Synopsis

A multipass optoacoustic cell and a color center laser have been used to record Doppler-limited overtone spectra of carbonyl sulfide in the spectral region between 6130 and 6650 cm 01 . To obtain spectra around 12 000 cm 01 we used a phase modulation diode laser spectrometer. Eight bands of 16 O 12 C 32 S and two bands of 16 O 12 C 34 S could be detected and assigned for the first time. Comparing the spectra with the results of a global rovibrational analysis gives an agreement within 0.05 cm 01 . In some cases the effect of the l resonance was calculated in a local model, in order to show its influence on the rotational energies.

Eleven very weak overtone bands of 14 N 2 16 O have been newly detected by intracavity laser absorption spectroscopy between 10 000 and 12 000 cm -1 . The rotational analysis of three others has been significantly improved. The vibrational assignment of the upper states of the observed transitions h
