✦ Synopsis

All available transitions from microwave to visible region (0.2-12 105 cm À1 ) of the HD 18 O molecule were collected and tested using the RITZ computer code. Literature data were completed by transitions assigned to HD 18 O in long path Fourier transform absorption spectra of the H 2 O, HDO and D 2 O gas mixtures with natural abundance of oxygen-18. In addition about 40 unassigned lines between 4200 and 6600 cm À1 of our previous water study associated with the HD 18 O molecule have been found and assigned. The new long path absorption spectra of the HDO and D 2 O mixtures allow us to observe about 1000 transitions of HD 18 O in the 6125-10 720 cm À1 spectral region. These data have been critically analyzed and used to obtain the most complete and precise set of the experimental energy levels of this molecule.
