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:

    “The instincts of the ant are very unimportant, considered as the ant’s; but the moment a ray of relation is seen to extend from it to man, and the little drudge is seen to be a monitor, a little body with a mighty heart, then all its habits, even that said to be recently observed, that it never sleeps, become sublime.”
    —Ralph Waldo Emerson (1803–1882)
