WebCrystal Field Splitting. 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.
