	* "diradical" means it has two remaining lone electrons. It does '''not''' mean that there are two dangling bonds in the sense of empty binding orbitals. Instead the two unpaired electrons are actually in the anti-binding pi-orbitals.		* "diradical" means it has two remaining lone electrons.

	* "triplet state" means that the remaining electrons have parallel spin. In the case of oxygen this increases the activation energy barrier. {{todo\|look into how in the case of oxygen the unpaired spins lead to strongly reduced reaction rates -- I'd suspect "forbidden" transitions due to parity conservation -- requiring a third reaction partner … or so …}}		* "triplet state" means that the remaining electrons have parallel spin.
