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, 1H...

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

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-depleted water (DDW) is water which has a lower concentration of deuterium than occurs naturally at sea level on Earth. DDW is sometimes known...

Deuterium–tritium fusion (sometimes abbreviated D+T) (DTF) is a type of nuclear fusion in which one deuterium (2H) nucleus (deuteron) fuses with one tritium...

remain in common use today: 2H is deuterium and 3H is tritium. The symbols D and T are sometimes used for deuterium and tritium; IUPAC (International...

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...

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...

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...

contains one proton and no neutrons, and that of non-radioactive hydrogen-2 (deuterium) contains one proton and one neutron. Tritium is the heaviest particle-bound...

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

interest, deuterium–deuterium muon-catalyzed fusion has been frequently observed and extensively studied experimentally, in large part because deuterium already...

used deuterium-deuterium fusion, which produced a 2.45 MeV neutron in half of the reactions. The IPA experiments claimed 300 km/s velocities, deuterium neutron...

out of natural water the heavy water (deuterium oxide = D2O) which is used in particle research, in deuterium NMR spectroscopy, deuterated solvents for...

Triatomic hydrogen or H3 is an unstable triatomic molecule containing only hydrogen. Since this molecule contains only three atoms of hydrogen it is the...

naturally occurring hydrogen atoms. Deuterium (2H) contains one neutron and one proton in its nucleus. Deuterium is stable, makes up 0.0156% of naturally...

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...

stable hydrogen isotope, is known as deuterium and contains one proton and one neutron in the nucleus. Nearly all deuterium in the universe is thought to have...

Proposed fusion reactors generally use heavy hydrogen isotopes such as deuterium and tritium (and especially a mixture of the two), which react more easily...

abundance of deuterium in comet Hale–Bopp in the form of heavy water was found to be about twice that of Earth's oceans. If Hale–Bopp's deuterium abundance...

accelerating either deuterium, tritium, or a mixture of these two isotopes into a metal hydride target which also contains deuterium, tritium or a mixture...
