Integral trace of NMR?

Can anyone inform me on how to read integral trace for NMR? It's hampering me from doing doing a few of the BR passages.

I'm stuck with example 2.23 on page 136 of BR organic chem section 2 if anyone has the book.

I believe you meant to say orgo section 1.
Anyways, to get better at learning to read CNMR and HNMR, I think you should first learn n+1 rule proton coupling; spin-spin splitting. Try typing these in youtube or something since it's difficult to teach with text especially if you are a visual person.
Once you master those, you should memorize specific shift values such as:
carbonyl, hydroxyl, methyl, benzene shifts, alkenes, alkynes, aldehyde, and carboxylic acids (those are what I could think right now).

You don't have to know all of the values listed on the table in the TBR book. Once you practice you will get used to memorizing them with time.

Hope this helped

I saw this too, and I also didn't quite know what to make of their squiggly "integral" line. Hopefully on the real thing it will be more clear or labeled.

Anybody have any input though in case it isn't?

I can't explain it any better than that site can
