Coupling causes the peaks in 1H NMR spectra to be split into two peaks multiple peaks equal to the number of hydrogen on surrounding atoms, plus one multiple peaks equal to the number of hydrogens on surrounding atoms multiple peaks equal to the number of surrounding carbon atoms 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 Blocking parts of a molecule from Rf radiation Using a curved piece of metal to block an opponents attack Putting metal around an Rf source 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 Expensive solvents work best with NMR They dissolve polymer the fastest NMR uses least of this solvent TRUE ANSWER : ? YOUR ANSWER : ?
All hydrogen atoms resonate at different frequencies depending on their environment. are attached to carbon have the same resonance frequency resonate at about the same frequency as carbon TRUE ANSWER : ? YOUR ANSWER : ?
What is used to cool the superconducting coil? Liquid helium Dry ice Ice Hydrogen TRUE ANSWER : ? YOUR ANSWER : ?
Better understanding of the nuclei is possible, with the help of a mathematical translator called the fourier transfer algorithm None of these with the help of wavelength spectrum with the help of frequencies ranges TRUE ANSWER : ? YOUR ANSWER : ?
