Solid-state nuclear magnetic resonance (NMR) spectroscopy—a technique that measures the frequencies emitted by the nuclei of some atoms exposed to radio waves in a strong magnetic field—can be used to ...

When two solutions of oppositely charged polymers (polyelectrolytes) are mixed, phase separation occurs and leads to the formation of a polymer-rich phase and a supernatant phase. The precise ...

Nuclear magnetic resonance (NMR) spectroscopy is perhaps the most useful technique in the organic chemist’s toolkit. But conventional NMR requires the sample to be placed in a very high magnetic field ...

NMR makes use of specific stable isotopes, commonly 13 C, but there is only one NMR-active stable isotope for oxygen, 17 O. The effects of using this oxygen isotope over other isotopes include lower ...

Nuclear magnetic resonance (NMR) spectroscopy represents a technique that is dependent on the magnetic properties of the atomic nucleus. When positioned in a strong magnetic field, certain nuclei ...

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.

Determining alcohols using NMR spectroscopy is carried out in order to introduce students to NMR spectroscopy at an early stage in their undergraduate career. The experiment aims to enable students to ...

Resonance” is right there in the name of nuclear magnetic resonance spectroscopy, but the technique doesn’t make most chemists think of music. Ayyalusamy Ramamoorthy, a biophysical chemist at the ...
