Talk:Configuration interaction

I think the use of the superscript SD here should be changed as it normally does not indicate spin orbitals, but rather configurations that are single and double excitations from the Hartree-Fock reference configuration. What do others think? I am happy to make the changes and also add material about CIS and CISD. Bduke 04:55, 31 October 2005 (UTC)[reply]

Well, I created this page, but I don't have the time to expand it right now. So go ahead and improve it if you'd like. Be bold! Karol 09:46, 31 October 2005 (UTC)[reply]

Thanks, Karol. I have had a go at it. Feel free to correct it. Bduke 01:50, 1 November 2005 (UTC)[reply]

units

I'm trying to figure what most of this means from the bottom up, and so I have a question. What are the units (if any) for Ψ? 65.78.17.194 01:44, 9 October 2006 (UTC)[reply]

Ψ doesn't have any units: the value of Ψ² at a point gives the probability of the electron being located at that point, so it doesn't have units either. Ian 07:56, 30 July 2007 (UTC)[reply]

history

who first developed this method?is it older than Moller Plsset perturbation theory?~
