Röser, B. The charge distribution in a molecule is usually discussed with respect to two interacting effects: An inductive effect, which is a function of the electronegativity differences that exist between atoms and groups ; and a resonance effect, in which electrons move in a discontinuous fashion between parts of a molecule.
