  2. Deuterated DMSO - Wikipedia

    13 C NMR Spectrum of DMSO-d 6. Pure deuterated DMSO shows no peaks in 1 H NMR spectroscopy and as a result is commonly used as an NMR solvent. [2] However commercially available samples are not 100% pure and a residual DMSO-d 5 1 H NMR signal is observed at 2.50ppm (quintet, J HD =1.9Hz). The 13 C chemical shift of DMSO-d 6 is 39.52ppm (septet ...

    en.wikipedia.org/wiki/Deuterated_methanol

    Deuterated methanol (CD 3 OD), is a form (called an isotopologue) of methanol (CH 3 OH) in which the hydrogen atoms ("H") are replaced with deuterium (heavy hydrogen) isotope ("D"). [1] Deuterated methanol is a common solvent used in NMR spectroscopy .

  6. Paramagnetic nuclear magnetic resonance spectroscopy

    en.wikipedia.org/wiki/Paramagnetic_nuclear...

    The difference between the chemical shift of a given nucleus in a diamagnetic vs. a paramagnetic environment is called the hyperfine shift.In solution the isotropic hyperfine chemical shift for nickelocene is −255 ppm, which is the difference between the observed shift (ca. −260 ppm) and the shift observed for a diamagnetic analogue ferrocene (ca. 5 ppm).

  7. Proton nuclear magnetic resonance - Wikipedia

    en.wikipedia.org/wiki/Proton_nuclear_magnetic...

    The CH 2 peak will be split into a doublet by the CH peak—with one peak at 1 ppm + 3.5 Hz and one at 1 ppm − 3.5 Hz (total splitting or coupling constant is 7 Hz). In consequence the CH peak at 2.5 ppm will be split twice by each proton from the CH 2. The first proton will split the peak into two equal intensities and will go from one peak ...

  8. Carbon-13 NMR satellite - Wikipedia

    en.wikipedia.org/wiki/Carbon-13_NMR_satellite

    Note, if the main 1 H-peak has proton-proton coupling, then each satellite will be a miniature version of the main peak and will also show this 1 H-coupling, e.g. if the main 1 H-peak is a doublet, then the carbon satellites will appear as miniature doublets, i.e. one doublet on either side of the main 1 H-peak. For other NMR atoms (e.g. 19 F ...

  9. Nuclear magnetic resonance spectroscopy of stereoisomers

    en.wikipedia.org/wiki/Nuclear_magnetic_resonance...

    Mosher's acid contains a -CF 3 group, so if the adduct has no other fluorine atoms, the 19 F NMR of a racemic mixture shows just two peaks, one for each stereoisomer. As with NMR spectroscopy in general, good resolution requires a high signal-to-noise ratio , clear separation between peaks for each stereoisomer, and narrow line width for each peak.
