Science - Chemistry; Chem Sci/Eng / stretching vibration
English term or phrase: stretching vibration
(1) The absorption at 3258cm-1 is the stretching vibration νN-H of amide, the absorption at 1649cm-1 、 1539cm-1 is respectively the stretching vibration νC=O of amide and deformation vibration δN-H of amide. So, it can be inferred that this compound contains the structure of amide group.
(2) The absorption at 1742cm-1 is the stretching vibrationνC=O of quarternary cyclic amide. So, it can be inferred that this compound contains the structure of quarternary cyclic amide.
(3) The absorption at 1608cm-1, 1399cm-1 is respectively asymmetric stretching vibration νC=O and symmetrical stretching vibration νC=O of carboxylate. So, it can be inferred that this compound contains the structure of carboxylate.

¿Puede ser "vibración de estiramiento"?

MUCHAS GRACIAS
