  2. Deuterated chloroform - Wikipedia

    en.wikipedia.org/wiki/Deuterated_chloroform

    Deuterated chloroform is a general purpose NMR solvent, as it is not very chemically reactive and unlikely to exchange its deuterium with its solute, [9] and its low boiling point allows for easy sample recovery. It, however, it is incompatible with strongly basic, nucleophilic, or reducing analytes, including many organometallic compounds.

  3. 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 ...

    en.wikipedia.org/wiki/Fluorine-19_nuclear...

    A sample 19F NMR spectrum of a simple organic compound. Integrations are shown under each peak. 19F NMR spectrum of 1-bromo-3,4,5-trifluorobenzene. The expansion shows the spin–spin coupling pattern arising from the para-fluorine coupling to the 2 meta-fluorine and 2 ortho proton nuclei.

  5. Carbon-13 nuclear magnetic resonance - Wikipedia

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

    For these reasons, 13 C-NMR spectra are usually recorded with proton NMR decoupling. Couplings between carbons can be ignored due to the low natural abundance of 13 C. Hence in contrast to typical proton NMR spectra, which show multiplets for each proton position, carbon NMR spectra show a single peak for each chemically non-equivalent carbon ...

  6. 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. Deuterated DMSO - Wikipedia

    en.wikipedia.org/wiki/Deuterated_DMSO

    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 ...
