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)
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. — Preceding unsigned comment added by 203.101.233.39 ( talk) 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)
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??
Perhaps it would be useful to add that the splitting of orbitals under any type of symmetry can be easily deduced from the character tables (for example for d-orbitals in octahedral symmetry: look up z2, x2, xy, xz, yz, you will find eg and t2g). Though to figure out how the energies of the orbitals relate to one another chemical intuition (for the simple cases) or computation (for the more complicated ones) is required 94.210.104.70 ( talk) 13:31, 17 October 2014 (UTC)
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)
Can u calculate CFSE for square pyramidal complexes. If u can please solve for any d-system. Aejaz Ul Bashir ( talk) 18:47, 30 July 2020 (UTC)
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)
I don't know who thinks that Fe has 5 d-elektrons, but it has 6.
I'm thinking of creating crystal field stabilization energy as a subarticle of this one...thoughts? -- HappyCamper ( talk) 23:41, 24 December 2007 (UTC)
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)
There are a few compounds that could be accommodated in the Spectrochemical series mentioned in the article. Some of them being EDTA, EtOH, etc. If no one has objections, I'll do the edits in a day or two

This appears to show a diagram of an insertion reaction instead of the orbital energy levels? Anareon ( talk) 16:47, 20 January 2011 (UTC)
The square planar splitting diagram is wrong. The dz2 should be a higher energy state than dxy. — Preceding unsigned comment added by Hunterbender ( talk • contribs) 14:26, 4 October 2012 (UTC)
There are many weaknesses in this article. I recommend An introduction to transition-metal chemistry, Ligand-Field theory by Leslie E. Orgel, Methuen (1960) for a clear introduction to the topic. Petergans ( talk) 10:47, 6 January 2017 (UTC)
I think this page should include the crystal field splitting for linear and trigonal coordination entities like diamminesilver(I), dicyanidoaurate(I), triiodomercurate(II) etc. Sayan Ghosh 12:56, 11 February 2018 (UTC)
The pattern of splitting is: dx2-y2 dz2 dxy dxz dyz and Crystal field splitting parameter is: D = dxy---->dx2-y2 But i need to know what is the energy of each orbital as per (del)° Aejaz Ul Bashir ( talk) 18:45, 30 July 2020 (UTC)
I'm considering updating the splitting diagrams that I made 14 years ago. The current ones look pixelated and generally low quality. -- YanA ( talk) 11:28, 5 November 2021 (UTC)

Hi there,
there's a point that seems unclear to me, in the article as well as in all the courses I found on this topic. The first step of the reasoning for crystal field theory goes like: "if the metal ion is surrounded by a spherical shell of negative charges, the electrostatic repulsion (between the shell and the electrons of the ions) leads to an increase of the orbitals energy". I would expect that the repulsion would generate a decrease in energy: adding an outer negative shell reinforces the electric field oriented from the nucleus to the outside, the electrons are "forced" towards the nucleus and more energy is required to release them (higher binding energy = lower (more negative) energy of the orbital). Can someone clarify this? 87.86.104.114 ( talk) 05:52, 15 April 2022 (UTC)
