Wasn’t that 1500 whatever-the-unit-was? Below 1000 whatever-the-unit-was was the fingerprint bands, 3400ish whatever-the-unit-was was the O-H bonds, 3100ish whatever-the-unit-was was N-H bonds, 2900ish whatever-the-unit-was was the triple-to-C-H bonds, etc.

Ugh. The lab portion for that was so tedious. We would have to sketch the expected resonance patterns by hand for a bunch of different molecules. I loved the simplicity of the hydrogen bond nuclear resonance imaging so much more.
