Question 1

All hydrogen atoms

Accepted Answer

resonate at different frequencies depending on their environment.

Question 2

What is shielding in NMR?

Accepted Answer

When the magnetic moment of an atom blocks the full induced magnetic field from surrounding nuclei

Question 3

What is used to cool the superconducting coil?

Accepted Answer

Liquid helium

Question 4

Better understanding of the nuclei is possible,

Accepted Answer

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

Question 5

Coupling causes the peaks in 1H NMR spectra to be split into

Accepted Answer

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

Question 6

Why is it important to use a deuterated solvent?

Accepted Answer

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

Question 7

When placed in a magnetic field, all the random spins of the nuclei

Accepted Answer

align with the magnetic field
