1. The primary photochemical process may get backtracked due to any reason. 2. The broken molecules may combine with each other resulting in the formation of the original molecule. 3. Activated molecules lose its energy before they get react further. 4. Collision of excited molecule with non excited ...

According to Lambert-Beer law, when a beam of monochromatic radiation passes through any solution, the intensity of the beam reduces to some amount. Let if I0 is the intensity of incident beam and It is the intensity of transmitted beam, then the intensity of energy ...

According to the principle of photochemical activation, only that part of the light which is absorbed by any system can cause photochemical change or reaction. However this is not essential that every time, the energy which is absorbed by any system can bring about a ...

Today photochemistry has become one of the most powerful research tool. Compounds of different molecules are occurred through various photochemical reactions like CO₂, NH₃ and methane. Other examples of photochemical reactions are formation of O₃, smog, Vitamin D and many more. A new field in ...

Photochemistry is the branch of science which deals with chemical reactions, reactions which occurred by the absorption of light waves which are called photons of energy. Only the radiations which fall under the region 800 nm to 200 nm can cause such reactions. Also the ...
