Talk:Triatomic hydrogen

Why?

"The molecule can only exist in an excited state."--Makecat (talk) 05:52, 20 November 2011 (UTC)

Otherwise it is more stable as a hydrogen molecule and a hydrogen atom seaparate from each other. |The Pauli exclusion principle prevents there from being more than two electrons in a bond between atoms, so you can have two atoms connected with two electrons (or one in H2+) or you can have two electrons between three atoms as in H3+, In this case you can imagine H3+ with one extra electron popped up into a higher level orbital. Higher level orbital means excited. Graeme Bartlett (talk) 06:36, 20 November 2011 (UTC)

I see. Thanks. --Makecat (talk) 09:32, 20 November 2011 (UTC)

article merge

H3 is tritium so shouldn't this article be merged with tritium ? — Preceding unsigned comment added by 86.148.236.48 (talk) 12:13, 7 April 2012 (UTC)

No. H₃ is not ³H. Tritium and triatomic hydrogen are different. ChemNerd (talk) 17:20, 9 April 2012 (UTC)

calculated on a computer?

The first paragraph talks about this trimer being "just simple enough to numerically solve the quantum mechanics description of the particles. More complex molecules with four electrons or more cannot be quantitatively simulated by computers."

This is not really accurate: you can simulate more complex molecules with a computer, just with increasing levels of approximation. I suspect that the hydrogen trimer wavefunction can't be solved without some approximation either, so perhaps we should work out exactly what the original intention behind this statement was. Is it that with a particular version of a configuration interaction calculation, you can simulate this, but nothing more complicated? More research needed. H123 wiki (talk) 07:11, 14 May 2015 (UTC)

I've gone and changed the bit saying that anything more complicated can't be solved on a computer. The reference that was given doesn't seem to apply to it (although I can't actually see that reference). It also dates back to 1989. It might be that in 1989, nothing more complicated could be solved accurately. Nowadays, systems with millions of atoms can be simulated using DFT, both because computers are faster and also because more efficient methods are known. I'd suggest that if there is a specific calculation that can be done on H3 but not anything more complicated, this could be added. H123 wiki (talk) 16:14, 16 May 2015 (UTC)
