  2. Deuterated acetone - Wikipedia

    en.wikipedia.org/wiki/Deuterated_acetone

    Deuterated acetone ((CD 3) 2 CO), also known as acetone-d 6, is a form (isotopologue) of acetone (CH 3) 2 CO in which the hydrogen atom (H) is replaced with deuterium (heavy hydrogen) isotope (2 H or D). Deuterated acetone is a common solvent used in NMR spectroscopy. [1]

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

    Occasionally, small peaks can be seen shouldering the main 1 H NMR peaks. These peaks are not the result of proton-proton coupling, but result from the coupling of 1 H atoms to an adjoining carbon-13 (13 C) atom. These small peaks are known as carbon satellites as they are small and appear around the main 1 H peak i.e. satellite (around) to

  4. 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 .

  6. Nuclear magnetic resonance spectroscopy - Wikipedia

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

    The chemical shifts of a molecule change slightly between solvents, and therefore the solvent used is almost always reported with chemical shifts. [ citation needed ] Proton NMR spectra are often calibrated against the known solvent residual proton peak [ 16 ] as an internal standard instead of adding tetramethylsilane (TMS), which is ...

  7. Carbon-13 NMR satellite - Wikipedia

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

    Carbon satellites in physics and spectroscopy, are small peaks that can be seen shouldering the main peaks in the nuclear magnetic resonance (NMR) spectrum.These peaks can occur in the NMR spectrum of any NMR active atom (e.g. 19 F or 31 P NMR) where those atoms adjoin a carbon atom (and where the spectrum is not 13 C-decoupled, which is usually the case).

  8. Deuterated chloroform - Wikipedia

    en.wikipedia.org/wiki/Deuterated_chloroform

    Commercial chloroform-d does, however, still contain a small amount (0.2% or less) of non-deuterated chloroform; this results in a small singlet at 7.26 ppm, known as the residual solvent peak, which is frequently used as an internal chemical shift reference. In carbon-13 NMR spectroscopy, the sole carbon in deuterated chloroform shows a ...

  9. Spectral Database for Organic Compounds - Wikipedia

    en.wikipedia.org/wiki/Spectral_Database_for...

    If a spectrum of an unknown chemical compound is available, a reverse search can be carried out by entering the values of the chemical shift, frequency or mass of the peaks in the NMR, FT-IR or EI-MS spectrum respectively. This type of search affords all the chemical compounds in the database that have the entered spectral characteristics. [6]
