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.

ECHEMI Editorial Reference

colourless liquid
Dideuterium oxide is a deuterated compound and a water.|Deuterium Oxide is a stable, non-radioactive isotopic form of water, containing 2 atoms of deuterium (D) and one atom of oxygen (2D2O), with DNA-labeling activity. Upon ingestion of deuterium oxide, 2H is incorporated into the deoxyribose moiety of DNA of newly divided cells. Rapidly dividing cells, as in the case of B-cell chronic lymphocytic leukemia (B-CLL), can be labeled with deuterium oxide and measured using gas chromatography and/or mass spectrometry.|The isotopic compound of hydrogen of mass 2 (deuterium) with oxygen. (From Grant and Hackh's Chemical Dictionary, 5th ed) It is used to study mechanisms and rates of chemical or nuclear reactions, as well as biological processes.
