Better understanding of the nuclei is possible, None of these with the help of wavelength spectrum with the help of frequencies ranges with the help of a mathematical translator called the fourier transfer algorithm TRUE ANSWER : ? YOUR ANSWER : ?
What is shielding in NMR? 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 TRUE ANSWER : ? YOUR ANSWER : ?
What is used to cool the superconducting coil? Liquid helium Dry ice Ice Hydrogen TRUE ANSWER : ? YOUR ANSWER : ?
All hydrogen atoms resonate at about the same frequency as carbon have the same resonance frequency resonate at different frequencies depending on their environment. are attached to carbon TRUE ANSWER : ? YOUR ANSWER : ?
When placed in a magnetic field, all the random spins of the nuclei stop align with the magnetic field reverse direction rotate to 90° away from the induced field TRUE ANSWER : ? YOUR ANSWER : ?
Why is it important to use a deuterated solvent? 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 TRUE ANSWER : ? YOUR ANSWER : ?
Coupling causes the peaks in 1H NMR spectra to be split into multiple peaks equal to the number of hydrogen on surrounding atoms, plus one multiple peaks equal to the number of surrounding carbon atoms multiple peaks equal to the number of hydrogens on surrounding atoms two peaks TRUE ANSWER : ?
