debye

plural debyes

1. natural sciencesThe CGS unit of electric dipole moment, defined as 1 D = 10⁻¹⁸ statcoulomb-centimetre and computable from the SI unit coulomb-metre by multiplying by the factor 3.33564 × 10⁻³⁰.

   The dipole moments of water and the alcohols are about 1.8 debyes. The moments of ethers are smaller, about 1.2 debyes.
