Preferred Label : resonance;
IUPAC definition : 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.;
