Bonjour, (désolée j'envoie le message un peu tard😅 ) mais j'ai une question sur l'item 42 : "Sur le spectre, on note la présence de plusieurs bandes d’élongation de liaison Car-Car entre 1456 et 1597 cm-1."

Pourquoi est-il vrai? La bande à 1597cm-1 ne correspond pas à la vibration d'élongation des doubles liaisons carbone-carbone?
