✦ Synopsis

From spectra recorded at a resolution of 0.020 cm 01 of the flame CH 4 / O 2 at low pressure, six new vibrational transitions in D£ 3 Å 1 with 2£ 1 / £ 2 Å 5 had been recently identified [ D. Bailly et al., J. Mol. Spectrosc. 182, 10 -17 ( 1996 ) ] based on the HITRAN 92 predictions. New calculations have shown good consistency with our assignments except for one transition, namely, ( 21 1 1 ) 3 e r ( 21 1 0 ) 3 e for which discrepancies ( reaching 0.2 cm 01 ) were found. It has been possible to resolve this issue using new emission spectra of CO 2 , vibrationally excited by active nitrogen and recorded with a Fourier transform spectrometer at a resolution of 6.3 1 10 03 cm 01 in the 4 -5 mm spectral region.

The experimental technique which consists of exciting a mixture of N 2 O and N 2 by radio frequency is very efficient for populating very high vibrational levels. Twelve emission spectra of mixtures of N 2 O and N 2 were recorded with a Fourier transform spectrometer at resolutions of 0.006, 0.004,

The HNC molecule was generated by the reaction of translationally hot H atoms with either ClCN or BrCN. The energetically rich HNC products were probed by time-resolved infrared laser absorption spectroscopy. This allowed for the spectroscopic analysis of 16 vibrational bands in the wavelength regio
