dipole moment
Dipole moment A mathematical quantity characteristic of a dipole unit equal to the product of one of its charges times the vector distance separating the charges. The dipole moment μ associated with a distribution of ()  electric charges qi is given by where r i is the vector to the charge qi. For systems with a net charge (for example, positive), the origin is taken at the mean position of the positive charges (and vice versa). Dipole moments have the dimensions coulomb-meters. Molecular dipole moments were previously expressed in debye units, where 1 debye = 3.336 × 10-30 C · m. See Dipole dipole moment[′dī‚pōl ‚mō·mənt] (electricity) electric dipole moment (electromagnetism) magnetic dipole moment (physical chemistry) The vector sum of the bond moments in a molecule, a measure of the polarity of the molecule. dipole moment
