[edit] Bond strength

Ah, goodie...we updated the bond strength of the molecule. I was using Chemical Structure and Bonding by R.L. DeKock and H.B. Gray (1989). --HappyCamper 19:33, 24 May 2006 (UTC)

[edit] Good article!

Although it's a tad on the technical side, I enjoyed this article. Thanks for putting it together! — RJH (talk) 16:35, 18 January 2007 (UTC)

[edit] Article title

I'm not convinced that protonated molecular hydrogen is the best title for this article. From what I've seen in the literature, most people call it H3+, although I understand that it might not be the best title on Wikipedia. As an alternative, I propose trihydrogen cation or triatomic hydrogen cation. Both are listed as possible names by CAS, unlike protonated molecular hydrogen. Here's the full list:

CA Index Name: Hydrogen, ion (H31+) (8CI,9CI)
Other Names: Hydrogen, H3+ ion (6CI); H3+; H31+; Hydrogen (H3+); Hydrogen (H31+); Hydrogen molecular ion (H3+); Hydrogen triatomic ion (H31+); Hydrogen triatomic ion(1+); Hydrogen triatomic monocation; Hydrogen triatomic monopositive ion; Hydrogen trimer ion(1+); Triatomic hydrogen (H31+); Triatomic hydrogen cation; Triatomic hydrogen cation(1+); Triatomic hydrogen ion(1+); Triatomic hydrogen mol. ion(1+); Trihydrogen cation (H3+); Trihydrogen ion(1+); Trihydrogen monocation; Trihydrogen(1+)

Why is it not a good title for Wikipedia? There used to be a restriction that the software would not allow article titles with plus signs, but that has been fixed. H3+ --HappyCamper 22:21, 8 June 2007 (UTC)
I thought using a formula as a title might be discouraged by the style guide, but perhaps I'm mistaken. --Itub 23:27, 8 June 2007 (UTC)
I don't know about that. Wikipedia is so big now that there are too many things to remember. How about moving it to H3+ ion? I've always called this "H-three-plus" though. Has less syllables than any of the alternatives above. --HappyCamper 23:56, 8 June 2007 (UTC)
I've looked for related guidelines. Wikipedia:Naming conventions (technical restrictions)#Plus says that the plus sign may give some trouble, but it's not too bad of a trouble, and is used for C++. Wikipedia:Naming conventions#Prefer_spelled-out_phrases_to_abbreviations may or may not apply, depending on whether you consider H3+ an abbreviation. A precedent, although not a guideline, is that the article E=mc2 was renamed to Energy-mass equivalence. In any case, I don't really like H-three-plus--that is one says it, but it looks odd in writing (E=mc2 is not bad, but imagine E equals em cee square!). My favorite is still trihydrogen cation, with all the others as redirects. --Itub 09:10, 9 June 2007 (UTC)
Oops, this page got lost on my watchlist. OK, I've warmed up to trihydrogen cation and moved the page too. --HappyCamper 12:24, 25 June 2007 (UTC)

[edit] In an ionic compound?

Can H3+ from any ionic compounds apart from being in a plasma? The article does not mention if any search has been conducted for this kind of substance - eg H3+I- GB 11:36, 25 June 2007 (UTC)

I'm pretty sure that it does not form any stable compounds other than itself in interstellar space. It does exist as an intermediate in some terrestrial reactions, but I don't know anything about them. --jdigangi 22:25, 26 July 2007 (UTC)

Thanks, recently I read that some one was predicting that it may be stable in solid noble gases such as solid neon. But as yet not tested. GB 12:13, 27 July 2007 (UTC)

[edit] Ortho/para

While technically interesting, of what use is this phenomenon? Are astrophysicists exploiting it for some sort of interstellar NMR? --Belg4mit (talk) 21:48, 14 April 2008 (UTC)
