Its proper molecular formula is H2H but for simplification it is usually written as HD. Preparation and occurrenceIn the laboratory it is produced by treating sodium hydride with deuterated water:[1] NaH + D2O → HD + NaOD Hydrogen deuteride is a minor component of naturally occurring molecular hydrogen. It is one of the minor but noticeable components of the atmospheres of all the giant planets, with abundances from about 30 ppm to about 200 ppm. HD has also been found in supernova remnants,[2] and other sources.{{cn|date=May 2012}}
Radio emission spectraHD and H2 have very similar emission spectra, but the emission frequencies differ.[3] The frequency of the astronomically important J = 1-0 rotational transition of HD at 2.7 THz has been measured with tunable FIR radiation with an accuracy of 150 kHz.[4] {{see also|rotational spectroscopy}}References1. ^{{cite journal|title=Preparation and Spectroscopic Properties of the η2-Dihydrogen Complexes [MH(η2-H2)PR2CH2CH2PR2)2]+ (M = Iron, Ruthenium; R = Ph, Et) and Trends in Properties Down the Iron Group Triad|authors=Bautista, Maria T.; Cappellani, E.
