Zusammenfassung	Ligand Field Theory (LFT) is an advanced model of metal-ligand bonding that combines crystal field theory with molecular orbital theory. Developed systematically by Brian Norman Figgis and others from the 1960s onward, LFT provides quantitative predictions of electronic structure, magnetism, spectra, and reactivity of coordination complexes, bridging the gap between qualitative crystal field arguments and rigorous quantum mechanics.	Crystal Field Theory (CFT) is a model that explains the electronic structure, color, magnetism, and reactivity of coordination complexes by considering how the electric field created by surrounding ligands perturbs the d-orbitals of a central metal ion. Developed by Hans Bethe in 1929 and refined throughout the 20th century, CFT is one of the most powerful tools for understanding inorganic chemistry.
