Photochemistry is the branch of chemistry that deals with the chemical processes that are caused by the absorption of light energy. A photochemical reaction is a chemical reaction initiated by the absorption of energy in the form of light (photons), resulting in specific products. Usually, molecules prefer to remain in the state of lowest energy, known as the ground state. When they are excited by photons, molecules absorb energy and goes into a transient state, known as the excited state. In this state, the physical and chemical properties of the molecules are entirely different from that of the ground state.
