Lines belonging to the ground vibrational state were observed from J”=1 toJ”=11. Several absorption lines were also detected in v 4=1 (Π), v 5=1 (Π), v 4=2 (Σ andΔ), v 5=2 (Σ and Δ), v 4=v 5=1 (Σ − , Σ + and Δ), v 4=3 (Π and Φ) and v 5=3 (Π and Φ). Thetransitions detected in this work were fitted together with all the infrared lines availablein literature for the bending states. The global fits allowed a very accurate determinationof the spectroscopic parameters of these molecules.
