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.

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 ...

We used two distinct methods to analyze the spectrum: determination of lipid ... the discriminatory capacity of multivariate analyses of NMR spectroscopic data is not high enough to render the ...

Solution-state nuclear magnetic resonance (NMR) spectroscopy is the classical NMR spectroscopy approach used for molecular structure determination, where the experimental sample is studied while ...

Applications testing at 1.3 GHz proton frequency was conducted using ... yielding high-resolution liquids and solids NMR spectra at 1.3 GHz. The results demonstrated increased resolution and ...
