Photolysis

 

the decomposition of molecules that occurs when the molecules absorb light. The decomposition products may be molecules with a smaller number of atoms, free radicals or atoms, or positive and negative ions. If the products are free radicals or atoms, the process is called photodissociation. If the products are positive and negative ions, the process is known as photoionization.
