The chemical reaction which is occur by the absorption of the light or photon is called as Photochemical reaction. And the branch of the chemistry which is dealing with the study of these types of reactions is called as photochemistry. Photochemical reaction are also called as light reaction, because they have got the activation energy from the light.
In this article we have covered the important aspects of photochemistry. Like the various rules of photochemistry which are the base of photochemical reaction and the important phenomena Jablonski Diagram which states about the mechanism of photochemical reaction and various light radiation process which are happened by the electronic transitions. We have also discussed the Quantum Yield by which we can determine about the number of molecules activated or decomposed by absorption of single photon. Including the Quantum Efficiency which gives the description about the efficiency of the Photosensitive Devices and also with the types of photochemical reaction with examples, which gives the idea about the various chemical reaction which are types of photochemical reactions.
