The region from 530 to 570 cm-1 shows intense absorption due to the v6(Πu) band system, of which the fundamental band only has been assigned and analysed, giving v6=540•221 cm-1. The region 590 to 660 cm-1 shows weaker absorption due to the v5(Πg) band system appearing in combination with odd quanta of the v7(Πu) fundamental at 18 cm-1. The v5 + v7 band and several hot bands have been assigned and analysed, and the effective v7 bending potential in the v5 state has been deduced. This potential shows a splitting as the large amplitude bending coordinate q7 is displaced due to interaction between v5 and v7 analogous to the Renner-Teller effect in electronic spectroscopy. This splitting is about 4 cm-1 for the classical turning points in q7 and the mean q7 bending potential is closely similar to that in the ground state.
