In particular, the Universe today is far more lumpy and contains far less deuterium than can be accounted for without dark matter.

The molecules of such water contain deuterium, heavy form of hydrogenwith an extra neutron in each molecule.

It is one of the only phenethylamines that contain deuterium, the other being beta-D.

Hydrides containing deuterium are known as deuterides.

Acidic protons may also be suppressed when a solvent containing acidic deuterium ions (e.g. methanol-d) is used.

But only in 1988 were Livermore scientists able to tap enough power to prove that intense X-rays could ignite fusion in a tiny plastic capsule containing deuterium and tritium.

Chloroform containing deuterium (heavy hydrogen), CDCl, is a common solvent used in NMR spectroscopy.

Water from rivers and lakes tends to contain less deuterium than seawater.

Comets that formed in colder regions have a relatively high ratio of heavy water (containing deuterium, an isotope of hydrogen) to regular water.

In the Earth's oceans, only about 1.6 in every 5,000 water molecules contain deuterium, so if we're looking for sources for our planet's water, we need to find bodies that have a similar ratio.
