resonance
In the context of chemistry, the term refers to the representation of the
electronic structure of a molecular entity in terms of contributing structures. 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
valence bond methods. The resulting stabilization is linked to the quantum mechanical concept of ‘resonance energy’. The term resonance is
also used to refer to the delocalization phenomenon itself.
