Noun
NMR spectroscopy (countable and uncountable, plural NMR spectroscopies)
(analytical chemistry) An analytical technique that exploits fine differences in the frequency of nuclear magnetic resonance in protons (and C atoms, etc.) within organic compounds that depends on their neighbouring atoms.
Whereas 1 H NMR spectroscopy is generally not useful for establishing the presence of a ketone, 13 C NMR spectra exhibit signals somewhat downfield of 200 ppm depending on structure. Source: Internet
Methods for the structure determination of oligosaccharides and polysaccharides include NMR spectroscopy and methylation analysis. Source: Internet
His second major contribution to the field of NMR spectroscopy was the experimental demonstration of the “two-dimensional” NMR technique first introduced by Jean Jeener at the 1971 AMPERE Summer School. Source: Internet
More convincing are the correlations between electronegativity and chemical shifts in NMR spectroscopy citation or isomer shifts in Mössbauer spectroscopy citation (see figure). Source: Internet
Protein structures from NMR spectroscopy also show helices well, with characteristic observations of nuclear Overhauser effect (NOE) couplings between atoms on adjacent helical turns. Source: Internet
