Structural Elucidation: NMR spectroscopy is widely used to determine the structures of organic and inorganic molecules. It can provide detailed information about the connectivity of atoms, the arrangement of functional groups, and the stereochemistry of molecules. NMR can be used to determine the structures of small organic compounds, complex natural products, proteins, nucleic acids, polymers, and more.

Compound Identification: NMR spectroscopy is a powerful tool for compound identification. By comparing the NMR spectrum of an unknown compound to a database of reference spectra, chemists can determine the identity of the compound. This is particularly useful in fields such as pharmaceuticals, forensics, and environmental analysis.

Quantitative Analysis: NMR spectroscopy can be used for quantitative analysis, allowing the determination of the concentration or purity of a compound in a mixture. This is achieved by comparing the integrals of NMR peaks to known standards or internal references.

Drug Discovery and Development: NMR spectroscopy plays a crucial role in drug discovery and development. It is used to study the interactions between drug molecules and their targets, such as proteins or DNA. NMR can provide information about binding affinities, binding sites, and structural changes upon binding, aiding in the design and optimization of drug candidates.

Metabolomics: NMR spectroscopy is employed in metabolomics, which involves the comprehensive analysis of small molecules (metabolites) present in biological samples. NMR-based metabolomics can provide insights into metabolic pathways, biomarker discovery, and the understanding of disease mechanisms.

Material Science: NMR spectroscopy is used to study the structure and dynamics of materials, such as polymers, catalysts, porous materials, and semiconductors. It can provide information about molecular mobility, phase transitions, and the arrangement of atoms in the material.

Imaging: NMR imaging, commonly known as MRI (Magnetic Resonance Imaging), is a non-invasive medical imaging technique that uses NMR principles to visualize internal structures of the body. MRI is widely used for diagnostic purposes in medicine, providing detailed images of soft tissues, organs, and abnormalities.

These are just a few examples of the broad range of applications of NMR spectroscopy. Its versatility, non-destructive nature, and ability to provide detailed structural information make it an indispensable tool in many scientific disciplines.
