Usage notes

In the context of chemistry, guidelines of the International Union of Pure and Applied Chemistry (IUPAC) recommend that deuterium and tritium be called by the chemical symbols “2H” and “3H”, in preference to “D” and “T”, respectively. [1][2] Thus, the preferred notation for diatomic tritium is “3H2” rather than “T2”.
