Passages with IR and NMR spectroscopy

For such passages, will they always include IR and NMR values for the compounds or molecules in question?

I looked through the practice passages in BR Organic for the chapter on structure elucidation and they only showed an IR graph in the passage without including a table of values.

I'm wondering if this is something I have to memorize...

Thanks!

I've taken several AAMC's old practices and sometimes they expect you to know the wavenumbers in orgo passages. But it wasn't be something trivial like "what's the IR stretching wavenumber for a nitrile functionality." It'll be more like what numbers correspond to Carboxylic acid/carbonyl numbers as opposed to alcohols in a certain passage that deals with their reduction/oxidation rxns. They did not show a table with values.

According to The Berkeley Review, the official AAMC guide to MCAT even says to "know the important ones." Know generally what carbonyls/alcohols/amines correlate to and why they do so. But if you're short on time, don't bother. It'll be at most 2 points of the BS.

Same as above, but I would add alkynes/alkenes. I've been asked questions about their wavenumbers before, but the alcohols/carbonyls/carboxylic acids are definitely high yield.
