Making Sense About Dipole Moments

Although the method of dipole moments has recently been left somewhat in the shadow of other rapidly developing methods it is still an important tool for structural investigations in organic chemistry. It is used for determination of the type of a chemical bond ( polar or covalent) molecular geometry ( isomerism, valence angles etc.) mutual effects of atoms and groups (mesomeric electron shift, ortho effect, etc.) properties of complexes and so on. It also reflects the electron density distribution in molecule in different states. 1
