'''Deuterium''' is an isotope of [[hydrogen]] that has a different neutron absorption spectrum from that of ordinary hydrogen.  

'''Deuterium''' is an [[isotope]] of [[hydrogen]], with the [[nucleus]] composed of a [[proton]] and a [[nucleus]]. It has a different neutron absorption spectrum from that of ordinary hydrogen. Deuterium is stable, although it is roughly 6000 times less abundant than common hydrogen (whose nucleus contains no neutrons).

Deuterated molecules (in which hydrogens have been partially or fully replaced by deuterium) have similar properties to their hydrogen monologues. For example, [[Heavy water|deuterated water]] has a boiling point of 101.4 degrees [[Celsius]] compared to [[water|normal water]], with a boiling point of 100 Celsius.
