    The BMRB accepts depositions from research groups around the world. Deposition of data containing only NMR spectral data (with no coordinates data) is carried out through the BMRB site using the ADIT-NMR deposition system. [12] The types of data accepted include: NMR spectral parameters, relaxation data, and kinetic and thermodynamic data.

    A 900 MHz NMR instrument with a 21.1 T magnet at HWB-NMR, Birmingham, UK. Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique based on re-orientation of atomic nuclei with non-zero nuclear spins in an external magnetic field.

  5. Two-dimensional nuclear magnetic resonance spectroscopy

    en.wikipedia.org/wiki/Two-dimensional_nuclear...

    While 1D NMR is more straightforward and ideal for identifying basic structural features, COSY enhances the capabilities of NMR by providing deeper insights into molecular connectivity. The two-dimensional spectrum that results from the COSY experiment shows the frequencies for a single isotope, most commonly hydrogen (1 H) along both axes.

  6. Nuclear magnetic resonance crystallography - Wikipedia

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

    Nuclear magnetic resonance crystallography (NMR crystallography) is a method which utilizes primarily NMR spectroscopy to determine the structure of solid materials on the atomic scale. Thus, solid-state NMR spectroscopy would be used primarily, possibly supplemented by quantum chemistry calculations (e.g. density functional theory ), [ 1 ...

    Bruker 700 MHz nuclear magnetic resonance (NMR) spectrometer. Nuclear Magnetic Resonance (NMR) basic principles. Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are disturbed by a weak oscillating magnetic field (in the near field [1]) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic ...

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

    The Spectral Database for Organic Compounds (SDBS) is developed and maintained by Japan's National Institute of Advanced Industrial Science and Technology. 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.
