  2. Nuclear magnetic resonance spectra database - Wikipedia

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

    A database that was developed and maintained by the publisher John Wiley & Sons. This database included more than 700,000 NMR, IR and MS Spectra, statistics specific to the NMR spectra are not listed. The NMR data includes 1 H, 13 C, 11 B, 15 N, 17 O, 19 F, 29 Si, and 31 P. The data were in the form of graphically displayed line lists.

  3. Biological Magnetic Resonance Data Bank - Wikipedia

    en.wikipedia.org/wiki/Biological_Magnetic...

    The Biological Magnetic Resonance Data Bank (BioMagResBank or BMRB) is an open access repository of nuclear magnetic resonance (NMR) spectroscopic data from peptides, proteins, nucleic acids and other biologically relevant molecules. [1] The database is operated by the University of Wisconsin–Madison and is supported by the National Library ...

  4. Proton nuclear magnetic resonance - Wikipedia

    There are three different types of H atoms in ethyl acetate regarding NMR. The hydrogens (H) on the CH 3 COO− group are not coupling with the other H atoms and appear as a singlet, but the −CH 2 − and −CH 3 hydrogens of the ethyl group (−CH 2 CH 3) are coupling with each other, resulting in a quartet and triplet respectively.

  5. Spectral Database for Organic Compounds - Wikipedia

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

    The database is available in English and in Japanese and it includes six types of spectra: laser Raman spectra, electron ionization mass spectra (EI-MS), Fourier-transform infrared (FT-IR) spectra, 1 H nuclear magnetic resonance (1 H-NMR) spectra, 13 C nuclear magnetic resonance (13 C-NMR) spectra and electron paramagnetic resonance (EPR ...

  6. Nuclear magnetic resonance database method - Wikipedia

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

    Yoshito Kishi's group at Harvard University has reported NMR databases for 1,3,5-triols [1] 1,2,3-triols, 1,2,3,4-tetraols, and 1,2,3,4,5-pentaols. [2] The stereochemistry of any 1,2,3-triol may be determined by comparing it with the database, even if the remainder of the unknown molecule is different from the database template compounds.

  7. Nuclear magnetic resonance spectroscopy of carbohydrates

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

    Typical 1 H NMR chemical shifts of carbohydrate ring protons are 3–6 ppm (4.5–5.5 ppm for anomeric protons). Typical 13 C NMR chemical shifts of carbohydrate ring carbons are 60–110 ppm In the case of simple mono- and oligosaccharide molecules, all proton signals are typically separated from one another (usually at 500 MHz or better NMR ...

  9. NMR database - Wikipedia

    en.wikipedia.org/wiki/NMR_database

    NMR database (NMR = nuclear magnetic resonance) may refer to: Nuclear magnetic resonance spectra database, a collection of NMR spectra for a large number of compounds; Nuclear magnetic resonance database method, a strategy to identify the stereochemistry of certain chiral compounds
