NMR spectroscopy is a physicochemical analysis technique that is based on the interaction of an externally applied radiofrequency radiation with atomic nuclei. During this interaction there is a net ...

NMR spectra are typically collected in solutions made up of deuterated solvents due to the fact that a protonated solvent will yield large solvent peaks which may hide the solute’s spectral features.

A proton NMR spectrum. Signals are due to different metabolites, with their peak integrals equal to their amount. Along the y-axis the T1 recovery time constant for each peak in the absence (red) and ...

Multivariate analysis of 1 H-NMR spectra of blood sera was reported previously to predict angiographically defined advanced coronary artery disease (CAD) with >90% accuracy and specificity. The ...

NMR spectroscopy can be used to elucidate structures, quantify target compounds and enable synthesis reaction monitoring in real time. It is possible to easily integrate benchtop NMR instruments into ...

The food industry has become a truly global trade, with foodstuffs routinely being transported thousands of miles before reaching the end consumer. This has made it increasingly difficult to ...

Artemisinin is a drug commonly used to treat malaria. The drug can be produced in a semi-synthetic manner, or it can be extracted from the plant Artemisia annua (sweet wormwood). Figure 1 displays the ...

An improved technique for ultra-high-resolution NMR spectroscopy may prove useful for applications such as process optimization, metabolomics, and studies of intrinsically disordered proteins. The ...

Please prepare your samples in the designated area or under a hood, and not on top of the magnet. The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the ...
