✦ Synopsis

The high-resolution Fourier transform spectrum of the D 2 O molecule were recorded and analyzed in the region near 0.97 µm (10 200-10 440 cm -1 ) where the bands of the v = 4 (v = v 1 + v 2 /2 + v 3 ) polyad are located. Transitions belonging to the strongest band of the polyad, 3ν 1 + ν 3 , 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 4ν 1 . Upper states energies obtained on that basis were fitted with a Hamiltonian model which took into account resonance interactions between the states of the v = 4 polyad. The derived spectroscopic parameters reproduce the overwhelming majority of assigned transitions within experimental accuracy.
