    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 ...

  4. 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 ...

    2 H-SNIF-NMR is the official AOAC method for determining the natural vanillin. The abundance of five monodeuterated isotopomers for vanillin can be measured by 2 H-SNIF-NMR. The vanillin molecule is represented in figure 11, all observable sites for which the site specific deuterium concentrations can be measured are referenced with a number.

  9. Organobromine chemistry - Wikipedia

    en.wikipedia.org/wiki/Organobromine_chemistry

    Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. [2] Carbon–halogen bond strengths, or bond dissociation energies are of 115, 83.7, 72.1, and 57.6 kcal/mol for bonded to fluorine, chlorine, bromine, or iodine, respectively ...
