These stretches are shown as peaks on an IR spectrum. For example, the C=O bond stretch gives sharp, distinctive peak around 1700 cm-1. If you see this peak on your IR that means you have a carbonyl bond in your molecule. If you don’t see this peak that means your molecule does not have a carbonyl group.Characteristic IR Absorption Peaks of Functional Groups* Vibration Position (cm-1) Intensity* Notes Alkanes C-H stretch 2990 – 2850 m to s Alkenes ...

Ether Infrared spectra. The obvious way to know a molecule is an ether is to see a C-O peak, but no C=O or O-H, since the absence of a C=O or O-H stretch confirms it is not an ester, acid, or alcohol. The C-O stretch is found between 1000 and 1300. Aliphalic ethers give one strong asymmetric stretch around 1120, and a very weak symmetric ...
