The high-resolution Fourier transform spectrum of the HDO molecule was recorded and analyzed in the region 7600-8100 cm-1 where the weak vibration-rotation bands 3ν1 and ν1+ν2+ν3 are located. Because of the presence of strong local resonance interactions, transitions belonging to the 3ν2+ν3 and 6ν2 bands were assigned as well. Spectroscopic parameters of all four bands were estimated, which reproduce initial line positions with accuracy close to experimental uncertainties.
