Have you guys memorized these shifts. I understand how the NMR works, but the shifts are so similar, its difficult to decipher anything based on that.
If the protons are heavily shielded by electron donating atoms, then they tend to be upfield and if they are surrounded by electron withdrawing groups, they are found downfield at a lower magnetic field. Additionally, if chemically equvivalent protons are surrounded by lets says 3 protons, you follow the n+1 rule & you will find 4 peaks.
But what is the significance of intensity of these peaks.
They keep talking about the area under the peaks, how do you determine that.
It is needless to say that I kept ignoring this section.
