Crystal field splitting diagrams
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. … http://chemiris.labs.brocku.ca/%7Echemweb/courses/chem232/CHEM2P32_Lecture_11.html
