NMR Spectroscopy Why is it important to use a deuterated solvent? Expensive solvents work best with NMR They dissolve polymer the fastest So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition NMR uses least of this solvent Expensive solvents work best with NMR They dissolve polymer the fastest So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition NMR uses least of this solvent ANSWER DOWNLOAD EXAMIANS APP
NMR Spectroscopy All hydrogen atoms resonate at about the same frequency as carbon are attached to carbon resonate at different frequencies depending on their environment. have the same resonance frequency resonate at about the same frequency as carbon are attached to carbon resonate at different frequencies depending on their environment. have the same resonance frequency 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 When the magnetic moment of an atom blocks the full induced magnetic field from surrounding nuclei Using a curved piece of metal to block an opponents attack Putting metal around an Rf source Blocking parts of a molecule from Rf radiation When the magnetic moment of an atom blocks the full induced magnetic field from surrounding nuclei Using a curved piece of metal to block an opponents attack ANSWER DOWNLOAD EXAMIANS APP
