The Fourier transform spectrum of the ν2+2ν3 band of the HDO molecule was recorded with a resolution of 0.02 cm-1. The spectrum was rotational analysed and the spectroscopic parameters of the (0,1,2) state were estimated in terms of Watson's effective rotational Hamiltonian model and also the model in the Padé-Borel approximation form. They reproduce the upper energy levels with an accuracy close to the experimental uncertainty of 0.001 cm-1.
