NMR Spectroscopy Why is it important to use a deuterated solvent? Expensive solvents work best with NMR So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition They dissolve polymer the fastest NMR uses least of this solvent Expensive solvents work best with NMR So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition They dissolve polymer the fastest NMR uses least of this solvent ANSWER DOWNLOAD EXAMIANS APP
NMR Spectroscopy What is shielding in NMR? Putting metal around an Rf source Blocking parts of a molecule from Rf radiation Using a curved piece of metal to block an opponents attack When the magnetic moment of an atom blocks the full induced magnetic field from surrounding nuclei Putting metal around an Rf source Blocking parts of a molecule from Rf radiation Using a curved piece of metal to block an opponents attack When the magnetic moment of an atom blocks the full induced magnetic field from surrounding nuclei ANSWER DOWNLOAD EXAMIANS APP
