Concept explainers

NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

Question

Identify the important absorption bands.

Example:

Analysis
The amide exhibits absorptions above 1460 cm-1 for both its N—H and C=O groups: N—H (two peaks) at 3173 and 3348 cm-1; C=O at 1681 cm-1.

(Ps. This is an example only and not connected in the problem.)
