WebOne 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 ... WebSep 14, 2016 · The reaction, starting from the natural product santonin, was initiated by exposure to sunlight and is a stunning example of the dualistic simplicity and complexity often associated with photochemical reactions.
