Dipole Moment

Dipole moment can be defined as the product of magnitude of charge and the distance of separation between the charges. Dipole moment may refer to:

• Electric dipole moment, the measure of the electrical polarity of a system of charges
  • Transition dipole moment, the electrical dipole moment in quantum mechanics
  • 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
  • Nuclear magnetic moment, the magnetic moment of an atomic nucleus
• Topological dipole moment, the measure of the topological defect charge distribution
• The second order coefficient of the multipole expansion of a function
