Crystal field theory ligand field theory
WebThe following points will clearly state the limitations of crystal field theory: The assumption that the interaction between metal-ligand is purely electrostatic cannot be said to be very realistic. This theory takes only d-orbitals of a central atom into account. The s and p orbits are not considered for the study. WebThe 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. Attributed mainly to the works of the U.S. physicist J.H. Van Vleck, the ligand field theory evolved from the earlier crystal field theory, developed for ...

Crystal field theory (CFT) describes the breaking of degeneracies of electron orbital states, usually d or f orbitals, due to a static electric field produced by a surrounding charge distribution (anion neighbors). This theory has been used to describe various spectroscopies of transition metal coordination complexes, in particular optical spectra (colors).
