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 q_i is given by where r _i is the vector to the charge q_i. 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
