A computed list of HD 16 O infrared transition frequencies and intensities is presented. The list, VTT, was produced using a discrete variable representation two‐step approach for solving the rotation–vibration nuclear motions. The VTT line list contains almost 700 million transitions and can be used to simulate spectra of mono‐deuterated water over the entire temperature range that are of importance for astrophysics. The line list can be used for deuterium‐rich environments, such as the atmosphere of Venus, and to construct a possible ‘deuterium test’ to distinguish brown dwarfs from planetary mass objects.
