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.

Definition Definition Group of atoms that shape the chemical characteristics of a molecule. The behavior of a functional group is uniform in undergoing comparable chemical reactions, regardless of the other constituents of the molecule. Functional groups aid in the classification and anticipation of reactivity of organic molecules.
