Résumé : The room temperature high resolution infrared spectrum of C 2H 6 between 1330 and 1610cm -1, the region of the 6 and 8 fundamentals, has been re-investigated owing to the relevance of this spectral region in atmospheric and planetary applied research. The assignments of transitions from the ground vibrational state to the upper states v 6, v 8, v 4+v 12 and 2v 4+v 9 (4592 in total) and from the lower state v 4 to the upper state v 4+v 8 (1090 lines) have been considerably extended with respect to our previous work [F. Lattanzi, C. di Lauro and J. Vander Auwera, J. Mol. Spectrosc. 248 (2008) 134-145], especially for the hot transitions. In particular, three new series of perturbation activated transitions were found, with ΔK=±2, made observable by the resonance of the type l(Δl=±2, ΔK=±1) within v 8. Also, new P-transitions to v 6 were found, made observable by the x,y-Coriolis resonance with v 8, at the values of K from 15 to 18. The extension of the assignments in the high frequency wing of v 8 and their analysis allowed the discovery of two additional resonance interactions. The first interaction, a higher order Coriolis-type between v 8(±K, l=±1) and v 6(K±2, l=0), induces a few detectable transitions to v 6 with ΔK=3. The second interaction, of the type l(Δl=±2, ΔK=±1), comes to resonance between v 8(k=19, ±l=±1) and 2v 4+v 9 (k=±20, l=±1). This last resonance and the x,y-Coriolis resonance of v 6 and 2v 4+v 9 allows one to observe several transitions to the 2v 4+v 9 vibrational state. The extension of the assignments in the (v 4+v 8)-v 4 hot band allowed discovery of a resonance interaction of the type l(Δl=±2, ΔK=±1) between the states v 4+v 8 and 2v 4+v 12, in addition to their well known Fermi-type interaction. The K-values before and after the level crossing could be determined for both interactions. Better values were also determined for the J-structure parameters B, D J and D JK in the v 4 state, from 410 selected combination differences. Least squares fit calculations, performed on 2084 upper state energy levels for the cold system (RMS of 3.69×10 -3cm -1) and 500 for the hot system (RMS of 6.62×10 -3cm -1), required a more sophisticated Hamiltonian model than in our previous work.
