  2. Deuterated solvent - Wikipedia

    en.wikipedia.org/wiki/Deuterated_solvent

    Deuterated solvents are a group of compounds where one or more hydrogen atoms are substituted by deuterium atoms. These isotopologues of common solvents are often used in nuclear magnetic resonance spectroscopy .

  4. Nuclear magnetic resonance spectroscopy - Wikipedia

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

    For example, most 1 H NMR signals for most organic compounds are within 15 ppm. For 31 P NMR, the range is hundreds of ppm. [22] In paramagnetic NMR spectroscopy, the samples are paramagnetic, i.e. they contain unpaired electrons. The paramagnetism gives rise to very diverse chemical shifts. In 1 H NMR spectroscopy, the chemical shift range can ...

  5. Nuclear magnetic resonance spectra database - Wikipedia

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

    SDBS includes 14700 1 H NMR spectra and 13000 13 C NMR spectra as well as FT-IR, Raman, ESR, and MS data. The data are stored and displayed as an image of the processed data. Annotation is achieved by a list of the chemical shifts correlated to letters which are also used to label a molecular line drawing.

  6. Fluorine-19 nuclear magnetic resonance spectroscopy - Wikipedia

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

    19 F NMR chemical shifts in the literature vary strongly, commonly by over 1 ppm, even within the same solvent. [5] Although the reference compound for 19 F NMR spectroscopy, neat CFCl 3 (0 ppm), [6] has been used since the 1950s, [7] clear instructions on how to measure and deploy it in routine measurements were not present until recently.

  8. 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 ...

  9. Deuterated chloroform - Wikipedia

    en.wikipedia.org/wiki/Deuterated_chloroform

    Deuterated chloroform, also known as chloroform-d, is the organic compound with the formula CDCl 3. Deuterated chloroform is a common solvent used in NMR spectroscopy. [2] The properties of CDCl 3 and ordinary CHCl 3 are virtually identical. Deuterochloroform was first made in 1935 during the years of research on deuterium. [3]
