Incorrect

Shouldn't the triplet state show three energy levels (or spectral lines)? And shouldn't the singlet state only show one? (Also it is unclear whether the arrows represent transitions between levels on the energy axis, or orientations of individual particles.) Cesiumfrog (留言) 07:33, 12 January 2023 (UTC)

I don't think so. See wikipedia:triplet state (although that article is also very hard to follow for the lay person).

Explicitly show combinations for each state

From wikipedia:triplet state I think I've got a rough idea of why these states are named singlet/doublet/triplet. But it would be nice to have a sketch that explicitly illustrates it.

From my understanding so far

• For the singlet there is only one possible state:

Low energy  High energy
(pair)      (empty)

• For the doublet there are two possible states:

Low energy  High energy
(pair)      (up)
(pair)      (down)

• For the triplet there are three possible states. But somehow I would end up with four:

Low energy  High energy
(up)        (up)
(down)      (down)
(up)        (down)
(down)      (up)

Also, at wikipedia:Singlet_oxygen#Electronic_structure it doesn't seem that the contrast is between different energy levels at all. All variations in spin seem to be happening at exactly the same energy level for singlet and triplet states.

Note: WP admins have recklessly implemented a broad IP-range block, otherwise I would have commented in an article's Talk page.
