Photochemical reaction - Photosensitization, Light Activation ...
One type of photochemical reaction is the dissociation of a molecule into two fragments. Since it is the electrons that provide the bonding forces that hold atoms together into molecules, if the distribution of electrons within a molecule changes drastically, the bonding forces may also change. In photodissociation, also called photolysis, the ...
