Like ordinary water—H 2 0—each molecule of heavy water contains two ... This isotope of hydrogen is called deuterium, and heavy water's more scientific name is deuterium oxide, abbreviated ...

Finally, research on the deuterium molecule (D 2) has yielded improved ionization and dissociation energies, providing a critical test for quantum electrodynamics in molecular systems[5].

Particularly, D2O is shown as a universal probe to visualize and track metabolic dynamics of various biomolecules simultaneously — improving upon deuterium probes, which can only track a ...
