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

Famous quotes containing the word moment:

    I have, thanks to my travels, added to my stock all the superstitions of other countries. I know them all now, and in any critical moment of my life, they all rise up in armed legions for or against me.
    Sarah Bernhardt (1844–1923)
