Nuclear
Magnetic Resonance (NMR) spectroscopy is an analytical tool that provides
valuable information about the molecular structure of a material. NMR
is most commonly used to analyze soluble organic materials, such as solvents,
polymers, surfactants, and reaction intermediates. A variety of different
NMR experiments is possible to help determine chemical information. NMR
is nucleus specific, and different information can be obtained from each
atom in a sample, for example, H, C, P, Si, and F. Analyses of solid materials,
such as composites and cured adhesives, are also possible using specialized
equipment with high-intensity radio frequencies and high-speed sample
spinning.

- Composition
information about polymers and resins, including unsaturated
polyesters,
phenol-formaldehyde resins, acrylic adhesives, and other cross-linking
polymer materials.
- Complete
quantitative analyses of product formulations.
- Purity
assays of raw materials and products from experimental reactions.
- Quantitative
assays of individual species in mixtures.
- Kinetics
and reaction completion studies, either via sampling from a reactor
or in situ in the NMR instrument.
- Identification
of unknown organic materials.
- Composition
information about cured polymeric materials, inorganic solids, fossil
fuels, and other solid material using multinuclear solid state NMR techniques.
