Dipole moment refers to the quality of a system to behave like a dipole. Dipole moment is the measured polarity of a polar covalent bond. It is defined as the product magnitude of charge on the atoms and the distance between the two bonded atoms. Its common unit is debye and SI unit is Coulomb metre. Dipole moments may be measured by comparing the dielectric constant and refractive index of solutions, where the solvent does not have a permanent dipole; e.g. cyclohexane. The solution should contain a non-dissociated solute molecule of choice. Dipole moment may also 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 Magnetic dipole moment, the measure of the magnetic polarity of a system of charges Bond dipole moment, the measure of polarity of a chemical bond Electron electric dipole moment, the measure of the charge distribution within an electron Topological dipole moment, the measure of the topological defect charge distribution |
