Some say that the reason we find things that glow under UV light fascinating is because we cannot see the UV light they absorb but can see the visible light they emit. So, why does quinine absorb UV light the invisible component of sunlight that produces sun tans and sunburns! It is due to the structure of the quinine molecule, which enables it to take in energy in the form of invisible UV light and immediately radiate some of that same energy in the form of visible blue light.
