IR Spectroscopy Exam Hack: 30‑Second IR Speedrun

Cut your #OrganicChemistry IR spectroscopy analysis time to 30 seconds and spend the rest on NMR - where the most useful information lies. In this tips‑and‑tricks video, I show a first pass for obvious functional group signals (alcohol, carbonyl, alkene) and a second pass for the rarer ones (amine, carboxylic acid, alkyne, nitrile, benzene), plus what to ignore in the fingerprint and routine C‑H region so you don’t get bogged down.You’ll learn how to spot the diagnostic peaks fast, make quick cross‑references, and avoid “fishing” for noise. Perfect for Organic Chemistry students who want higher exam scores without memorizing giant IR tables.
