The high-resolution Fourier transform spectrum of the HDO molecule was recorded and analyzed in the region 6140-7040 cm−1 where the bands v1 + v3, 2v2 + v3, and 2v1 + v2 are located. The presence of strong local resonance interactions allowed us to assign some tens of transitions to the weak bands 5v2 and v1 + 3v2 as well. Spectroscopic parameters of the analyzed bands were estimated. They reproduce initial upper energies with the accuracy close to experimental uncertainties.
