NMR Spectroscopy
Tells us:
The number of different hydrogen environments (number of peaks)
The heights of the peaks tell us how many different hydrogen’s are in
each environment in their simplest ratio
The value of the peak tells us the chemical shift in the molecule which
then tells us what types of bonds are present in the molecule
Splitting in the peak identifies how many protons are in the environment
next door
...
This spectrum only works for H1 hydrogen atoms
...
Protons near an electronegative atom will have a higher ppm value
...
In order to stop this we use a deuterated solvent
which removes N-H and O-H peaks
