Organic Photochemistry Part I
Organic Photochemistry Part I Learning Objectives: In this unit we shall learn about the i) Basic Principles of Photochemistry. ii). Several photophysical processes . iii). Photochemical reactions of a few classes of organic compounds. INTRODUCTION Classical Chemistry : It involves the reactions of molecules in their ground electronic states. Photochemistry : It involves the reactions of molecules in excited electronic states. Organic photochemistry is the study of reactions that occur through excited states of organic molecules produced by the absorption of electromagnetic radiation in the UV-Vis region. Classical Chemistry & Photochemistry There are a few advantages of photochemistry over classical chemistry. 1.In photochemistry selective activation of individual reactant in a mixture of number of reactant is possible. 2.There is an activation energy requirement for every chemical reaction. However if the activation energy is very high, the desired reaction ca...
