what is exactly dipole moment

it is defined as the product magnitude of charge on the atoms and the distance between the two bonded atom.

Dipole moment can be defined as the product of magnitude of charge & distance of separation between the charges. Dipole momentmay refer to:

• Electric dipole moment, the measure of the electrical polarity of a system of charges
• Transition dipole moment, the electrical dipole moment in quantum mechanics
• Bond dipole moment, the measure of polarity of a chemical bond
• Electron electric dipole moment, the measure of the charge distribution within an electron
• Magnetic dipole moment, the measure of the magnetic polarity of a system of charges
• Nuclear magnetic moment, the magnetic moment of an atomic nucleus
• Molecular dipole moment, the electric dipole moment of a molecule.
• Topological dipole moment, the measure of the topological defect charge distribution
• The second order coefficient of the multipole expansion of a function
