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