The absorption spectrum of HDO has been recorded in the region 8558-8774 cm-1 using a high-sensitivity intracavity F2 -:LiF center laser spectrometer. The absorption sensitivity is 10-7 cm-1 and the line-center determination accuracy is about 4 × 10-2 cm-1. The spectrum was interpreted and the absorption lines were attributed to the ν2 + 2ν3 band of HDO. Energy levels up to J = 12 and rotational and centrifugal parameters of the vibrational (012) state were obtained.
