In the context of chemistry, the term refers to the representation of the electronic structure of a @[email protected] in terms of @[email protected] Resonance among contributing structures means that the wavefunction is represented by 'mixing' the wavefunctions of the contributing structures. The concept is the basis of the quantum mechanical @[email protected] bond methods. The resulting stabilization is linked to the quantum mechanical concept of '@[email protected]'. The term resonance is also used to refer to the @[email protected] phenomenon itself.
