21. Centrosymmetric environment are electric-dipole forbidden by the Laporte rule. 22. In stricter terms, these methods detect only the characteristic dipole moment. 23. Dipoles can be characterized by their dipole moment, a vector quantity.24. Dipoles can be characterized by their dipole moment, a vector quantity. 25. Dipole -dipole interactions are electrostatic interactions between permanent dipoles in molecules.26. Dipole-dipole interactions are electrostatic interactions between permanent dipoles in molecules. 27. Dipole-dipole interactions are electrostatic interactions between permanent dipoles in molecules. 28. Often molecules contain dipolar groups, but have no overall dipole moment. 29. The magnetic field of a magnetic dipole is depicted in the figure. 30. This can be reduced to a simple dipole using the superposition principle.
