Mass hydrogen isotopes
Hydrogen (1H) has three naturally occurring isotopes, sometimes denoted H , H , and H . H and H are stable, while H has a half-life of 12.32(2) years. Heavier isotopes also exist, all of which are synthetic and have a half-life of less than one zeptosecond (10 s). Of these, H is the least stable, while H is the most.

WebHydrogen isotopes in water are measured from H2 gas formed by reducing water with a suitable reducing agent like U, Zn, Cr or C. It is also possible to exchange hydrogen isotopes between H 2 gas and H 2 O in the presence of Pt catalysts. Ratios of HD to H 2 (mass 3 to 2) of the sample hydrogen gas are measured and reported as δD values.
