crystal field splitting energy

Crystal field splitting energy refers to the energy difference between electron orbitals in a transition metal ion when surrounded by a specific arrangement of nearby ions or molecules (ligands). These ligands create an electric field that splits the degenerate (equal-energy) d-orbitals into groups with different energies. The size of this energy gap influences the colors of compounds, their magnetic properties, and how they bond. In essence, it describes how the environment around a metal ion alters the energies of its electrons, affecting the compound’s physical and chemical characteristics.
