NMR Spectroscopy What is shielding in NMR? When the magnetic moment of an atom blocks the full induced magnetic field from surrounding nuclei Blocking parts of a molecule from Rf radiation Putting metal around an Rf source 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 Blocking parts of a molecule from Rf radiation Putting metal around an Rf source Using a curved piece of metal to block an opponents attack ANSWER DOWNLOAD EXAMIANS APP
NMR Spectroscopy When placed in a magnetic field, all the random spins of the nuclei rotate to 90° away from the induced field reverse direction stop align with the magnetic field rotate to 90° away from the induced field reverse direction stop align with the magnetic field ANSWER DOWNLOAD EXAMIANS APP
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
