When placed in a magnetic field, all the random spins of the nuclei reverse direction align with the magnetic field stop rotate to 90° away from the induced field TRUE ANSWER : ? YOUR ANSWER : ?
Coupling causes the peaks in 1H NMR spectra to be split into multiple peaks equal to the number of hydrogens on surrounding atoms multiple peaks equal to the number of hydrogen on surrounding atoms, plus one two peaks multiple peaks equal to the number of surrounding carbon atoms TRUE ANSWER : ? YOUR ANSWER : ?
What is used to cool the superconducting coil? Hydrogen Liquid helium Ice Dry ice TRUE ANSWER : ? YOUR ANSWER : ?
What is shielding in NMR? 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 TRUE ANSWER : ? YOUR ANSWER : ?
Why is it important to use a deuterated solvent? 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 TRUE ANSWER : ? YOUR ANSWER : ?
