The high-resolution absorption spectrum of the D2O molecule was recorded with the Fourier-transform intracavity laser absorption spectrometer in the region 12570-12820 cm-1 where the band 4ν1 + ν3 is located. Transitions belonging to the 4ν1 + ν3 band, and the bands 3ν1 + 2ν3 and 3ν1 + 2ν2 + ν3, of which the up states are strongly interacted with that of the 4ν1 + ν3, were assigned in the recorded spectrum. Up state energy levels were fitted to derive effective spectroscopic parameters, which reproduce majority of the assigned transitions within the experimental accuracy.
