The room temperature high resolution infrared spectrum of C2H6 between 1330 and 1610 cm−1, the region of the ν6 and ν8 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 ν6, ν8, ν4 + ν12 and 2ν4 + ν9 (4592 in total) and from the lower state ν4 to the upper state ν4 + ν8 (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 ν8. Also, new P-transitions to ν6 were found, made observable by the x,y-Coriolis resonance with ν8, at the values of K from 15 to 18. The extension of the assignments in the high frequency wing of ν8 and their analysis allowed the discovery of two additional resonance interactions. The first interaction, a higher order Coriolis-type between ν8(±K, l = ±1) and ν6(±K ± 2, l = 0), induces a few detectable transitions to ν6 with ΔK = 3. The second interaction, of the type l(Δl = ±2, ΔK = ∓1), comes to resonance between ν8(k = ±19, l = ±1) and 2ν4 + ν9 (k = ±20, l = ∓1). This last resonance and the x,y-Coriolis resonance of ν6 and 2ν4 + ν9 allows one to observe several transitions to the 2ν4 + ν9 vibrational state. The extension of the assignments in the (ν4 + ν8) − ν4 hot band allowed discovery of a resonance interaction of the type l(Δl = ±2, ΔK = ∓1) between the states ν4 + ν8 and 2ν4 + ν12, 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, DJ and DJK in the ν4 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 × 10−3 cm−1) and 500 for the hot system (RMS of 6.62 × 10−3 cm−1), required a more sophisticated Hamiltonian model than in our previous work.
