NMR SPECTROSCOPY QUIZ

reverse direction

align with the magnetic field

stop

rotate to 90° away from the induced field

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

Hydrogen

Liquid helium

Ice

Dry ice

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

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

resonate at about the same frequency as carbon

resonate at different frequencies depending on their environment.

are attached to carbon

have the same resonance frequency

None of these

with the help of a mathematical translator called the fourier transfer algorithm

with the help of frequencies ranges

with the help of wavelength spectrum
