Vibrational study of p, p′-disubstituted N-benzylideneanilines. Lo spettro del n-esano mostra forti bande di assorbimento a 2900 cm-1 che sono il risultato dei movimenti di stiramento (stretching) dei legami C-H.  A 1460 cm-1 abbiamo il bending  del CH2 e il bending asimmetrico del CH3, mentre a 1380 cm-1 si ha la deformazione simmetrica del CH3.  Poiché la zona 2000 - 1800 cm-1 è abbastanza sgombra sono facilmente visibili le cosiddette dita dell’aromatico, costituite da 2, 3 o 4 bande.

The increase in the CN(H) stretching frequency upon protonation is shown to be neither due to a negative CN/CNH coupling force constant nor due to the CN stretching but to be mainly due to the strong contribution from the large CNH bending force constant (1.08 mdyn/rad2) and a positive coupling constant (0.30 mdyn/rad). Patil. Due to the contributions of these two modes, the C=N stretching frequency is particularly sensitive to the magnitude of the Schiff base counterion interactions and to the hydrogen bonding environment of the Schiff base nitrogen.
