CONT

Dans la théorie de la liaison de valence, [l'indice de liaison] est une moyenne pondérée [de la] multiplicité de liaisons entre les atomes des structures limites. (NdT : L'expression «liaison de valence» a été adoptée pour traduire le terme anglais «valence bond»). Par exemple, dans la théorie de la liaison de valence, l'indice de liaison entre deux atomes de carbone adjacent du benzène est 1,5; dans la théorie des orbitales moléculaires, il est 1,67.
