NMR SPECTROSCOPY QUIZ

two peaks

multiple peaks equal to the number of hydrogens on surrounding atoms

multiple peaks equal to the number of hydrogen on surrounding atoms, plus one

multiple peaks equal to the number of surrounding carbon atoms

So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition

NMR uses least of this solvent

They dissolve polymer the fastest

Expensive solvents work best with NMR

have the same resonance frequency

are attached to carbon

resonate at different frequencies depending on their environment.

resonate at about the same frequency as carbon

Ice

Hydrogen

Liquid helium

Dry ice

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

Using a curved piece of metal to block an opponents attack

reverse direction

rotate to 90° away from the induced field

align with the magnetic field

stop

with the help of frequencies ranges

None of these

with the help of wavelength spectrum

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