Preferred term

DEUTERIUM OXIDE/HEAVY WATER  

Definition

  • Deuterium oxide (D2O), aka “heavy water”, is the form of water that contains two atoms of the 2H, or D, isotope. The term heavy water is also used for water in which 2H atoms replace only some of the 1H atoms. In this case, rapid exchange between the two isotopes forms twice as many “semiheavy” HDO molecules as D2O. (en)
