ligand field theory
in chemistry, one of several theories that describe the electronic structure of coordination or complex compounds, notably transition metal complexes, which consist of a central metal atom surrounded by a group of electron-rich atoms or molecules called ligands. The ligand field theory deals with the origins and consequences of metal- ligand interactions as a means of elucidating the magnetic, optical, and chemical properties of these compounds.
