Nuclear magnetic resonance (NMR) | Metabolomics
Nuclear magnetic resonance (NMR) | Metabolomics

Nuclear magnetic resonance (NMR) NMR is an analytical technique that is used to measure organic and some inorganic compounds inside biological samples (as solid tissue or extracted metabolite). When a sample is exposed to a magnetic field and radio frequency (rf) pulse, the nuclei absorb and re-emit this electromagnetic radiation.

Nuclear magnetic resonance (NMR) is a physical process in which nuclei in a magnetic field absorb and reemit electromagnetic radiation. Analysis of NMR spectra allows the determination of polymer composition, and the distribution of monomer units can be deduced from the diad and triad sequences by NMR spectral analysis.
