Description NMR spectroscopy is a technique that relies on the phenomenon of nuclear magnetic resonance and can provide detailed information about the chemical structure of molecules. The technique relies on the fact that all subatomic particles (electrons, protons and neutrons) have the property of spin. NMR detects nuclei possessing spin.
This technique can be used to determine if the product is genuine or counterfeit but can also be used to identify unknown compounds such as impurities and contaminants including solvents, precursors, intermediates and decomposition products. It is usually possible to deduce the complete chemical structure of a product from NMR data (other spectroscopic techniques require an appropriate spectrum library for chemical structure confirmation).
 
Strengths Identification of the different compounds;
Possibility to exploit data for profiling (impurities, precursors etc..);

 
Limitations Requires specific equipment: the device and some training for the person who is manipulating the device;
Cost;
Destructive;
