  2. 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]

  4. Nuclear magnetic resonance spectroscopy - Wikipedia

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

    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. 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 ...

    Simple spectra predictions, including 13 C-NMR, 1 H-NMR (based on additive rules and functional group lookup methods), and IR [3] Simple property estimation, including p K a , octanol-water partition coefficient , and gas-phase enthalpy change.

  7. 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.

  8. Nuclear magnetic resonance spectra database - Wikipedia

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

    Available through Wiley Online Library [3] (John Wiley & Sons), SpecInfo on the Internet NMR is a collection of approximately 440,000 NMR spectra (organized as 13 C, 1 H, 19 F, 31 P, and 29 Si NMR databases). The data are accessed via the Internet using a Java interface and are stored in a server developed jointly with BASF. The software ...

  9. Chemical shift - Wikipedia

    en.wikipedia.org/wiki/Chemical_shift

    Chemical shift δ is usually expressed in parts per million (ppm) by frequency, because it is calculated from [5] =, where ν sample is the absolute resonance frequency of the sample, and ν ref is the absolute resonance frequency of a standard reference compound, measured in the same applied magnetic field B 0.
