Deuterium-depleted water
Deuterium-depleted water (DDW) is water which has a lower concentration of deuterium than occurs naturally at sea level on Earth.
DDW is sometimes known as light water or protium water, although " light water" has long referred to ordinary water ...

Semiheavy water
Semiheavy water is the result of replacing one of the protium (normal hydrogen, H) in normal water with deuterium (H; or D). It exists whenever there is water with H and H in the mix. This is because hydrogen atoms (H) are rapidly exchanged betw ...

Heavy water
Heavy water (deuterium oxide, , ) is a form of water (molecule), water in which hydrogen atoms are all deuterium ( or D, also known as ''heavy hydrogen'') rather than the common hydrogen-1 isotope (, also called ''protium'') that makes up most o ...
