IR Spectroscopy
Quick fact
IR spectroscopy can distinguish between two molecules that have the same atoms but different shapes (isomers) because their vibrational patterns differ.
Why this is interesting
You’ve seen how visible light reveals colors, but what if you could 'see' the invisible bonds that hold a molecule together? That’s exactly what IR spectroscopy does—it lets us identify molecules by their unique vibrational 'fingerprints'.
