A dipole moment is a measurement of the separation of two opposite electrical charges. Dipole moments are a vector quantity. The magnitude is equal to the charge multiplied by the distance between the charges and the direction is from negative charge to positive charge:
μ = q · r
where μ is the dipole moment, q is the magnitude of the separated charge, and r is the distance between the charges.
Dipole moments are measured in the SIunits of coulomb·meters (C m), but because the charges tend to be very small in magnitude, the historical unit for a dipole moment is the Debye. One Debye is approximately 3.33 x 10-30 C·m. A typical dipole moment for a molecule is about 1 D.
