Molecular Vibration

Molecular vibration refers to the periodic movement of atoms within a molecule, where bonds stretch, bend, or twist. These vibrations occur because atoms are constantly in motion, even at a constant temperature. When molecules vibrate, they can absorb or emit specific amounts of energy, often detectable as infrared light. These vibrations are fundamental to understanding a molecule’s properties and behavior. Think of atoms as connected by springs; when energy is added, the springs stretch or compress rhythmically, creating a pattern of vibrations essential for chemical reactions and interactions.
