Dans la méthode de la résonance, cet indice peut être considéré comme la moyenne pondérée des nombres de paires d'électrons liant deux atomes dans chacune des structures limites prises en considération ; ainsi dans le benzène, l'indice de liaison entre deux atomes de carbone est voisin de 1,5. 2, record 1, French, - indice%20de%20liaison
