STRUCTURE ELUCIDATION OF ORGANIC SUBSTANCE USING NMR SPECTROSCOPY
The chemical structure of an organic compound can be determined by NMR spectroscopy. Different atoms within a molecule resonate at different frequencies at a given field strength. The observation of the resonance frequencies of a molecule allows us discover structural information about the molecule. The structural elucidation based on intensive 1D and 2D NMR techniques.
