WebThis deviation from crystal field theory highlights the weakness of crystal field theory's assumption of purely ionic bonds between metal and ligand. The order of the spectrochemical series can be derived from the understanding that ligands are frequently classified by their donor or acceptor abilities. 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). CFT successfully accounts for some magnetic properties, colors, hydration enthalpies, and spinel structures of transition metal complex…
