Needs explanation as to why the release of heat is undesirable. -- Leonard G. 03:55, 19 Sep 2004 (UTC)
Why is orthohydrogen refered to as the triplet state, and parahydrogen is the singlet state?
If this page is correct (i.e. ortho- and para- hydrogen refer to alignment of the spins of the two protons in a H2 molecule, not alignment of electron and proton spins in a H atom), then there's a problem with http://en.wikipedia.org/wiki/SHGb02_14a . The problem is that in that article they are referring to alignment of electron and proton spins. I am assuming this article is correct, and removing the reference from the SHGb02_14a article to ortho- and para-hydrogen. 21:22, 30 March 2006 (UTC)
[edit] Rename?
Move to a more general and descriptive name like nuclear spin modifications of hydrogen or spin isomers of hydrogen? Femto 13:25, 10 August 2006 (UTC)
[edit] Question
Is there a significant difference in the energy released when para or ortho hydrogen is combined with oxygen to form water? I got the impression from a patent that one is less explosive than the other....??
[edit] Another question
How much heat? in other words how many kJ/mol is released when turning ortho into para hydrogen? —Preceding unsigned comment added by 87.10.127.103 (talk) 12:22, August 29, 2007 (UTC)
