With respect to the two splitting diagrams shown in the article, I think the tu orbitals should be labeled eg instead for an octahedral complex. I have taken the time to modify the diagrams shown and will upload them if any one concurs that it is more correct to label the tu orbitals as eg--YanA 06:42, 2 March 2006 (UTC)

Can't see any tu orbitals here Chris 05:50, 30 August 2006 (UTC)
Yeah, I changed that while ago.--YanA 09:45, 1 November 2006 (UTC)

Had quite a major rewrite, introducing high and low spin section. I propose to move ligand-field stabilisation here as well (and rename it crystal field stabilisation).--Chris 21:11, 24 May 2006 (UTC)

Propose move crystal field splitting to ligand field splitting. 23:12, 29 August 2006 (UTC)

I have changed the old .jpg images to .png images to remove the compression artifacts.--YanA 06:18, 10 November 2006 (UTC)

[edit] Explaining the colours of transition metal complexes

I have rewritten this, to make it a bit clearer. However, I feel much of it is misleading and should be removed. It implies that the energy of the photon absorbed is equal to Δ, which is simply not true for d2 to d9 complexes. These often absorb at two or three different wavelengths, none of which is equal to Δ. What is written here is a gross oversimplification. Thoughts??

OK, nobody said anything so I made a few changes to remove this problem.Chris 17:11, 29 December 2006 (UTC)

[edit] CFSE

I wrote a section on CFSE. It could with a diagram to illustrate the 2/5 - 3/5 splittng though, should anybody feel so inclined...Chris 19:47, 31 December 2006 (UTC)

I'll place it on my list of things to do.--YanA 01:45, 29 April 2007 (UTC)

[edit] Planned Work

  • Touching up grammar and content (i.e. more consistent use of Δ with and without subscripts.
  • Crystal field splitting diagrams for other geometries (most likely of similar quality to those already there).

I'll get to having most of this done by early June assuming no one objects to my plans or has other suggestions.--YanA 20:23, 30 April 2007 (UTC)

[edit] Iron

I don't know who thinks that Fe has 5 d-elektrons, but it has 6.

Um, iron(III) has 5. Chris 19:13, 18 May 2007 (UTC)

[edit] Split article?

I'm thinking of creating crystal field stabilization energy as a subarticle of this one...thoughts? --HappyCamper (talk) 23:41, 24 December 2007 (UTC)

[edit] Which English?

OK, not trying to start an argument here, but the article needs to be consistent as per WP:MOS. Any of you regulars know who was first and which English (UK or US) the article was started in? We've got both in there (e.g. colour and stabilization). I'm happy to edit it but I'm not about to start a war all over again :) Freestyle-69 (talk) 02:45, 8 April 2008 (UTC)

From looking at past versions of this article, it looks like it was started in American English, but it was transitioned to British English in late 2006 and early 2007.--YanA (talk) 04:10, 26 April 2008 (UTC)
Aha- just made a minor edit and saw this- thanks. I'll put it into US English as per WP:MOS#National varieties of English when I get some time. Cheers, Freestyle-69 (talk) 04:21, 28 April 2008 (UTC)
