11. The electric dipoles are unaligned and have no net polarisation. 12. Sometimes, to that list are appended other extensive state variables, for example electric dipole moment. 13. Electric polarisation is a result of aligned electric dipoles . 14. Van der Waals forces originate from the interactions between induced, permanent or transient electric dipoles . 15. The intensity of the Raman scattering is proportional to the electric dipole -electric dipole polarizability change. 16. The intensity of the Raman scattering is proportional to the electric dipole-electric dipole polarizability change. 17. This has an interesting consequence on the electric dipole moment ( EDM ) of any particle. 18. The electric dipole moment vector "'p "'also points from the negative charge to the positive charge. 19. Such charged pairs act as an electric dipole . 20. Likewise, the electric field from a magnetic dipole behaves like the magnetic field from an electric dipole .
