Crystal filed theory
WebThe crystal field theory (CFT) was introduced by Hans Bethe and J.H Van Vleck around 1930. CFT is based on the principle that the forces of attraction between a metal ion and the ligands present in a transition metal complex are purely electrostatic (100 % ionic). Web33.2.1 Crystal Field Theory. To explain the observed behavior of transition metal complexes (such as how colors arise), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field ...
