Extended sets of experimental energy levels of HD¹⁸O and D₂¹⁸O have been obtained as the result of the analysis of recent high-resolution spectra ^, and previously reported data ^,^,^,^,^,^,^, Spectra of the enriched by deuterium and oxygen-18 water samples were recorded with a Bruker IFS 120HR spectrometer at room temperature in the 1000~-~9200 cm^-1 range ^a,b for this purpose. The RITZ code ^h was used for analysis of the rotation-vibration transitions and the energy levels determination.

New energy levels as well as comparison with previous experimental and theoretical studies will be presented.
