The present book chapter has highlighted the various types of NMR spectroscopy,
including solid-state NMR, solution-state NMR, and their applications in hybridization with
other spectroscopic techniques in pharmaceutical analysis, drug discovery, and impurity
profiling. NMR has been a powerful tool for both drug discovery and the study of the structure
and dynamics of biomolecules in conjunction with X-ray crystallography. Along with other
chemometric techniques like principal component analysis, discriminant analysis, and partial
least square regression are used. In the pharmaceutical sector, NMR has been found to be much
important in determining the purity of medications with their various variants, the validity of
herbal products/heparin, fingerprinting of isotopes, etc.
Keywords: Applications of NMR, NMR spectroscopy, Nuclear magnetic resonance, Organic compounds, Solid-state NMR.
