The preferred method is based on the investigation of signals in the proton NMR spectrum associated with the lipoproteins. Variations in the size, composition, and density of lipoproteins ...

If these "magnetized" protons, neutrons, or electron can be cleverly brought ... In practical terms, almost any chemical element has a nuclear isotope that is NMR active. This makes NMR spectroscopy ...

"Pure shift" NMR spectra, also known as broadband homonuclear decoupling, has been developed for disentangling overlapped proton spectra. The resulting spectra are considerably simplified as they ...

A frequently documented NMR spectrum is the 1D 13 C carbon spectrum, which is less sensitive than the 1 H spectrum. Proton decoupling during the FID acquisition can boost its sensitivity (Figure 1).

These techniques are also difficult, and it is unusual to achieve proton line widths less ... In general solid-state NMR may produce more lines than you might have expected from the liquid spectrum.

with proton decoupling for the simplification ... system may become the new de facto standard in benchtop multinuclear NMR spectroscopy." ...

To mitigate and investigate food fraud, researchers use analytical methods, such as spectroscopy, to analyze the constituents of food. Recent technical advances in the design of NMR instrumentation ...
