Crystal field splitting f orbitals
According to crystal field theory, the interaction between a transition metal and ligands arises from the attraction between the positively charged metal cation and the negative charge on the non-bonding electrons of the ligand. The theory is developed by considering energy changes of the five degenerate d-orbitals upon being surrounded by an array of point charges consisting of the ligands. … WebGW correlation effects on plutonium quasiparticle energies: changes in crystal-field splitting.

WebSep 5, 2024 · To see that this makes sense, you can think about crystal field splitting as an electrostatics problem. The orbital has to pay an energy penalty if it points towards another ion with other electrons present.
