The calculations clearly show that the CN(H) stretching frequency and its deuterium isotope shift in protonated imines are significantly influenced by the CNH bending and the CN/CNH coupling force constants.

Queste sono bande multiple di altre presenti a 1000 o a 500 e sono relative a vibrazioni di scheletro C-C. Nello spettro IR dell’acetofenone bande di assorbimento leggermente superiori e leggermente inferiori ai 3000 cm-1 sono dovute rispettivamente a stretching C-H aromatici e alifatici. A poco meno di 3000 cm-1 cade l’assorbimento di stretching del legane C-H. Si noti  la presenza delle bande a 1378 e a circa 1470 cm-1 già analizzate in precedenza. Sharifkhani. Cruz, Clara S.B. La frequenza di stretching del legame C=C è più bassa nel caso degli aromatici (1500 cm-1) che non negli alcheni (1650 cm-1 circa).
