The photochemistry is the important field of chemistry. The photochemistry basically deals with the excitation, absorption and emission of photons by molecules, molecular ions, atoms, atomic ions, etc. The basic and easy to understand example of photochemical process is seen with the absorption and subsequent emission of a photon by a gas phase atom such as sodium. There are mainly two laws which govern these photochemical processes are:

(i)         I law (Grotthus – Draper Law) – the law states that the chemical change are produced only by the absorbed radiations. But there are some exceptions which does not follow this rule. These are electronic Raman Effect or inelastic scattering of X- or gamma rays.

(ii)       II law (Stark – Einstein Law) – the law states the number of quanta absorbed is equal to the number of excited molecules produced. The exception to this law is two–photon or multiphoton absorption (lasers).
