INTRODUCTION. Crystal field theory (CFT) is a bonding model that explains many properties of transition metals that cannot be explained using valence bond theory. In CFT, complex formation is assumed to be due to electrostatic interactions between a central metal ion and a set of negatively charged ligands or ligand dipoles arranged around the metal ion.

Crystal field theory (CFT) describes the breaking of orbital degeneracy in transition metal complexes due to the presence of ligands. CFT qualitatively describes the strength of the metal-ligand bonds. Based on the strength of the metal-ligand bonds, the energy of the system is altered. This may lead to a change in magnetic properties as well.

This book of crystal field theory describes all of the available phenomenological models, together with the conceptual and computational tools necessary for their use.

It will be of particular interest to graduate students and researchers working in the development of opto-electronic systems and magnetic materials. Scheme 1. Fermi surfaces illustrating the valence band convergence for rhombohedral (left) and cubic (right) GeTe.

The crystal field effect (c/a ratio) and s orbital energy (ε s > ε Te-p) of dopant are the critical factor to realize band convergence in rhombohedral and cubic GeTe, by: 8. The crystal field stabilization energy (CFSE) is the stability that results from placing a transition metal ion in the crystal field generated by a set of ligands.

It arises due to the fact that when the d -orbitals are split in a ligand field (as described above), some of them become lower in energy than before with respect to a spherical field known as the barycenter in which all five d -orbitals are degenerate.

This is expected for transition metal alloys with d -electron bonds, which are resistant to changes in bond angle and length. The incommensurate structures of quasicrystals also resist dislocation motion, further increasing the hardness and decreasing the ductility.

Overview of Crystal Field Theory. In order to understand clearly the crystal field interactions in transition metal complexes, it is necessary to have knowledge of the geometrical or spatial disposition of d orbitals.

The d-orbitals are fivefold degenerate in a free gaseous metal ion.
