Which electronic process explains why certain transition metal complexes exhibit intense colors in solution?

💡 Explanation

When transition metal ligands bind, ligand field splitting occurs because electrostatic interactions raise and lower the energies of the d-orbitals, which leads to light absorbance by promoting electrons making transitions between said d-orbitals. Therefore d-orbital ligand field splitting accounts for the colors, rather than bond variation or refraction index changes, needing different conditions.
