Important features of crystal field theory
WitrynaCrystal field effects resulting from interactions of the bonded atoms with electrons in partially filled 3d orbitals of Cr not only lead to the spectacular variety of colors characteristic of Cr compounds, but also to important fractionation processes of this element within and between minerals in the Earth. WitrynaThe first of the two main imminent features of the PCM is the additivity of the crystal field potential in the model with respect to its sources, which means that the …

It is the process of the splitting of degenerate level in the presence of ligand. The difference between the energy of t2g and eg level is denoted by “Δ o ”. There are some ligands producing strong fields and causing large crystal field splitting. On the other hand, others produce very weak fields.
