Preferred Label : mesomerism;
IUPAC definition : Essentially synonymous with resonance. The term is particularly associated with the
picture of π-electrons as less localized in an actual molecule than in a Lewis formula
(electron dot or Lewis structure). The term is intended to imply that the correct
representation of a structure is intermediate between two or more Lewis formulae.;
