Fourier transform emission spectra were recorded using a mixture of H 2 O and D 2 O at a temperature of 1500 • C. The spectra were recorded in three overlapping sections and cover the wavenumber range 380-2190 cm -1 . A total of 22 106 lines were measured, of which 60% are thought to belong to HDO.

✦ Synopsis
Fourier transform emission spectra were recorded using a mixture of H 2 O and D 2 O at a temperature of 1500 °C. The spectra were recorded in three overlapping sections and cover the wavenumber range 1800-3932 cm À1 . This spectrum is analyzed together with a previously reported one spanning the 380-2190 cm À1 range [Parekunnel et al., J. Mol. Spectrosc. 101 (2001) 28]. This analysis leads to 4409 newly assigned HDO emission lines. This work particularly extends data on the ( 200) and (120) states of HDO for which newly determined energy levels are presented.
