WebIn chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.It has particular value for analyzing … Web2 de jan. de 2024 · Here we develop a quantitative theory of chemical resonance based on semilocalized Clar-type resonance structures (named the Clar resonators) consisting of variable numbers of Clar sextets and C═C bonds. The constructed wave functions of the Clar resonators are used to expand the actual wave function of the π-conjugated system …

WebA. Mathematical and Physical Sciences. The theory of resonance in inorganic and organic chemistry was largely formulated in the period 1927 to 1933 on the basis of the quantum-mechanical theory of the singlet and triplet states of the helium atom that was developed by Heisenberg in 1926 and was given the name quantum-mechanical resonance by him.
