Abstract

The high-resolution Fourier transform spectrum of the D2O molecule were recorded and analyzed in the region near 0.97 μm (10 200-10 440 cm−1) where the bands of the ν = 4 (ν = ν1 + ν2/2 + ν3) polyad are located. Transitions belonging to the strongest band of the polyad, 3ν1 + ν3, are assigned up to the value of the rotational angular momentum quantum number J = 13. The presence of strong local resonance interactions allowed us to assign some transitions to the very weak band 4ν1. Upper states energies obtained on that basis were fitted with a Hamiltonian model which took into account resonance interactions between the states of the ν = 4 polyad. The derived spectroscopic parameters reproduce the overwhelming majority of assigned transitions within experimental accuracy.
