The quinine in tonic water will fluoresce under ultraviolet light. In fact, quinine will visibly fluoresce in direct sunlight against a dark background. [19] The quinine molecules release energy as light instead of heat, which is more common. The state is not stable, and the molecules will eventually return to a ground state and no longer glow ...
