Surface Tension

It is the force in dynes acting along the surface of the liquid 1cm in length and perpendicular to it.

Crystal Field Theory

Theory of bonding in transition metal complexes in which ligands and metal ions are treated as point charges, a purely ionic model, ligand point charges represent the crystal (electrical) field perturbing the metal?s d orbitals containing nonbonding electrons.

Polarization
