High accuracy line list of HDO

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.
