Nuclear Magnetic Resonance (NMR) Spectroscopy
Nuclear Magnetic Resonance (NMR) Spectroscopy is a powerful analytical technique that uses magnetic fields and radiofrequency signals to determine molecular structure, purity, and chemical environment. By observing how atomic nuclei respond to magnetic excitation, NMR provides detailed information about chemical bonds, functional groups, molecular connectivity, and conformation.
Materials Metric supports multiple NMR nuclei including ยนH (proton), ยนยณC (carbon), and ยนโนF, along with advanced 2D experiments such as COSY, HSQC, and HMBC for in-depth structural elucidation of polymers, organic compounds, and biomolecules.
Use of NMR Spectroscopy
NMR is used to:
โข Determine molecular structure and connectivity
โข Confirm polymer composition and branching
โข Identify impurities, degradation products, and side reactions
โข Measure monomer ratios, functional group conversions, and end groups
โข Evaluate biomolecules including peptides, metabolites, and natural compounds
Applications of NMR Spectroscopy
โข Polymers: composition, crosslinking, additive identification
โข Pharmaceuticals: purity, identity, stability testing
โข Biomaterials: polymer chemistry and functionalization
โข Organic Synthesis: structure verification and reaction monitoring
โข Natural Products: metabolite and compound identification
