dipolemoment
Dipole moment is a measure of the separation of positive and negative electric charges in a system, most commonly used to describe the polarity of a molecule. In chemistry, it is a vector quantity that reflects the asymmetry of the charge distribution; it points from the negative to the positive charge.
For a discrete set of charges, the dipole moment is defined as μ = ∑_i q_i r_i, where q_i
The unit most commonly used is the debye (D); 1 D ≈ 3.33564 × 10^-30 C·m. A nonpolar
Experimentally, dipole moments are inferred from rotational or microwave spectra and from dielectric measurements, and they
