Deuterium (hydrogen-2, symbol 2H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other is protium, or hydrogen-1)....

Deuterium fusion, also called deuterium burning, is a nuclear fusion reaction that occurs in stars and some substellar objects, in which a deuterium nucleus...

Deuterium NMR is NMR spectroscopy of deuterium (2H or D), an isotope of hydrogen. Deuterium is an isotope with spin = 1, unlike hydrogen-1, which has...

Heavy water (deuterium oxide, 2 H 2O, D 2O) is a form of water whose hydrogen atoms are all deuterium (2 H or D, also known as heavy hydrogen) rather than...

A deuterium arc lamp (or simply deuterium lamp) is a low-pressure gas-discharge light source often used in spectroscopy when a continuous spectrum in...

Deuterium–tritium fusion (sometimes abbreviated D+T) is a type of nuclear fusion in which one deuterium nucleus fuses with one tritium nucleus, giving...

Deuterium bromide is hydrogen bromide with the hydrogen being the heavier isotope deuterium. Hydrogen represents only a small fraction of the mass so...

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...

Hydrogen–deuterium exchange (also called H–D or H/D exchange) is a chemical reaction in which a covalently bonded hydrogen atom is replaced by a deuterium atom...

However, when deuterium is used instead of hydrogen, the deuterium fluoride lases at the wavelength of about 3.8 µm. This makes the deuterium fluoride laser...
