WebDec 18, 2013 · Summary Splitting of d-orbital degeneracy by a crystal field As we saw in the previous chapter the s - and p -orbital degeneracies are unaffected when an atom or ion is placed in a site of octahedral … 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… simple stone wall drawing
