Molecular Vibrations: The Invisible Dance of Atoms
Quick fact
Each molecule has a unique set of vibrational frequencies, like a fingerprint. This allows scientists to identify compounds by shining infrared light on them and seeing which frequencies are absorbed.
Why this is interesting
Have you ever thought of a molecule as a tiny, jiggling spring toy? Even at absolute zero, its atoms never stop vibrating—why does this perpetual dance happen, and what secrets does it reveal?
