  • Molecular dipole moment, the electric dipole moment of a molecule.
  • Bond dipole moment, the measure of polarity of a chemical bond
  • Electron electric dipole moment, the measure of the charge distribution within an electron
• Magnetic dipole moment, the measure of the magnetic polarity of a system of charges
  • Electron magnetic moment
  • Nuclear magnetic moment, the magnetic moment of an atomic nucleus
• Topological dipole moment, the measure of the topological defect charge distribution
• The first order term (or the second term) of the multipole expansion of a function
• The dielectric constant of a solvent; the measure of its capacity to break the covalent molecules into ions
