Deuterium, chemical symbol D or 2H is an isotope of the element hydrogen which has an extra proton. A compound containing deuterium is said to be deuterated. Deuterated chemicals are widely use in NMR spectroscopy, either as chemical shift references, as solvents, or to reduce the relaxation rates of NMR signals in large compounds like proteins. Deuterium is a stable, naturally occuring isotope of hydrogen and represents 0.015% of naturally occuring hydrogen, with H-1 representing the remaining 99.985%.
