What is the IR value of amide group?

Amide infrared radiation (IR) absorption spectral amide I (1600–1800 cm^–¹), II (1470–1570 cm^–¹), III (1250–1350 cm^–¹), and A (3300–3500 cm^–¹) bands are the famous IR characterizations of amide.

What are functional groups in IR?

Functional groups are the portions in an organic molecule that dictate how the molecule will react.
To generate the IR spectrum, different frequencies of infrared light are passed through a sample, and the transmittance of light at each frequency is measured.

IR SPECTRUM OF AMIDES The amide functional group combines the features of amines and ketones because it has both the N-H bond and the C=O bond. Therefore amides show a very strong, somewhat broad band at the left end of the spectrum, in the range between 3100 and 3500 cm-1 for the N-H stretch.
