Abstract
About 2000 lines of the four bands quoted in the title have been assig ned. A root-mean-square deviation of about 0.0235 cm(-1) has been achi eved by a least-squares fit over 1771 lines. For this purpose, a model involving 15 levels, linked either by the x-y Coriolis resonance betw een the v(2) and v(5) modes or by slight anharmonic resonances, was us ed. Several perturbations remain unexplained in the 3v(5)(+/-1) band, the centre of which is shifted by the Fermi resonance between the v(5) = 3(+/-1) and the (v(1) = 1, v(5) = 1(+/-1)) levels.
