Advanced Inorganic Chemistry/D4h Molecular Orbitals

WebCrystal Field Theory is a simple model which explains the spectra, thermochemical and magnetic data of many complexes. It's main flaw is that it treats the ligands as point charges or dipoles, and fails to consider the orbitals of the ligands. Ligand Field Theory applies molecular orbital theory and symmetry concerns to transition metal complexes.
