Résumé :

14 rovibrational bands are observed in the 1 micron region of the absorption spectrum of C2H2between 9300 and 10500 cm-1, and rotationally analysed. Transition induced dipole moments are estimated for all the cold bands involving upper levels of (Formula Presented)symmetry. Those various data are used to demonstrate the leading role of the 0030°0° level in the vibrational mixings and also to deal quantitatively with a possible picture of the couplings occurring among the cluster of levels in resonance with 0030°0°. © 1989 Taylor & Francis Ltd.
