WebOct 15, 2024 · Deuterium oxide (D 2 O), aka “heavy water”, is the form of water that contains two atoms of the 2 H, or D, isotope. The term heavy water is also used for water in which 2 H atoms replace only some of the 1 H atoms. In this case, rapid exchange between the two isotopes forms twice as many “semiheavy” HDO molecules as D 2 O..
