Royal Soc. 54 454 The symmetry of the electric charges makes null the aggregate electric moment. 1935 C. J. Smith Intermediate Physics (ed. 2) v. xxxvii. 622 In an unpolarized medium, if we assume a chaotic arrangement of atoms, the resultant electric moment per unit volume must be zero. 2002 G. A. Gallup Valence Bond Methods viii.111 When the bond is between unlike atoms, it is to be expected that ionic structures in the wave function will also contribute to various electric moments, the dipole moment being the simplest. < as lemmas |
