Actually how do the articles in the See also section Potential energy surface, Diabatic, Conical intersection, Avoided crossing,Vibronic coupling relate to the Jahn-Teller effect?V8rik 7 July 2005 15:02 (UTC)
- A complex may be found at a minimum of the potential energy surface after undergoing a Jahn Teller distortion process. Most of the other references are related to this, but I'm still not sure about the conical intersection and vibronic coulping. -- Rune Welsh ταλκ July 7, 2005 15:16 (UTC)
- Check this article [1] if you can. It explains the relationship between conical intersection and Jahn-Teller effects quite nicely. -- Rune Welsh ταλκ July 7, 2005 16:15 (UTC)

- I have introduced those links because they are evident to me. A Jahn-Teller effect occurs when two potential energy surfaces are crossing for some symmetry reason. This is just the case where the Born-Oppenheimer approximation fails, i.e. when the vibronic coupling cannot be neglected. In such case the Diabatic representation is the best one. This of course corresponds also to a conical intersection. But I am not a specialist and I would not like to write to much stupidity about this. That's the reason why I have not commented all this that much.
[edit] octahedral complex
the Jahn-Teller effect is a pretty advanced topic in chemistry and a reader would really benefit from some groundwork, octahedral complex would be preferable over octahedral complex. See also the AXE method, most molecular geometries are still missing. V8rik 20:07, 12 July 2005 (UTC)
[edit] preservation of inversion center
I'm pretty new to this Wiki editting but I thought I'd start here. The Jahn-Teller effect preserves the inversion center, if present in the 'original' complex. Source is “Inorganic Chemistry” 4th ed., Huheey, Keiter, Keiter (HKK), pages 499-455. I doubt this source helps as it's not available online for viewing. I think it'd be important to add this preservation in the article. Heymon32 05:50, 6 February 2007 (UTC)
- OK, I added a sentence to that effect. The general rule in Wikipedia is: Be bold. If you want to make a sensible change, go for it! Chris 09:04, 6 February 2007 (UTC)
