ligand field theory
Metal-orbital splitting explanation
Ligand field theory explains how metal atoms in chemical compounds interact with surrounding molecules or ions (ligands).
It describes how these ligands affect the energy levels of a metal's electrons, which in turn determines the compound's color, magnetism, and reactivity.
The theory combines earlier crystal field theory with molecular orbital concepts, and is fundamental to understanding transition metal chemistry: Ligand field theory explains why copper sulfate is blue.
