WebThe process of photodegradation is well understood by chemists. In general, when light strikes a molecule, it may initiate any number of reactions that result in the destruction of that molecule. For example, light may dislocate one or more electrons that make up a chemical bond in the molecule. When the bond is broken, the molecule is destroyed.
