Course Description: Photochemistry is a science that deals with photo and chemical changes. This course covers the basic principles of photochemistry and present real-world applications, so that students can gain an understanding of chemical changes that are influenced by photoreactions. Course Areas The major areas of this course are included in the following chapters: - Photochemical principles

4 - Chemical changes III. Photophysics IV. Concerted reaction V. Photochemistry in nature.] Course Objectives Objectives of the course are concentrated around the above areas as follows: 1- Photochemical principles after careful study of this chapter the student should be able to a) Define the photochemistry b) Distinguish absorption and emission process c) Describe the nature of light d) Define Einstein s work e) Distinguish between electric and magnetic fields. f) Describe the action of light with matter. g) Compare between spontaneous and simulated emission. h) Describe the electronic transition i) State photochemistry laws 2- Chemical changes after careful study of this chapter the student should be able to a) Define types of photochemical reactions. b) List the factors determining reactivity c) Describe Jablonski diagram d) Compare between types of singlet oxygen reactions. e) Understand Cis cyclic mechanism f) Describe Diels Alder reaction g) Describe photodissociation reaction h) Compare between Norish type I and Norish type II i) Distinguish inter & intra molecular cyclo addition 3- Photophysics after careful study of this chapter the student should be able to a) Distinguish pathways for loss of electronic excitation b) Describe the differences between three types of cold lights c) Define the Fluorescence and its electronic transition d) Know the process of phosphorescence radiation e) Define Chemiluminescence f) Give example of cold light applications Concerted reaction after careful study of this chapter the student should be able to a) Define concerted reaction b) Define Major categories of pericyclic reactions c) Describe electrocyclic closure ring\opening ring d) Describe cycloaddition reactions e) Explain sigmatropic rearrangement f) Draw Frontier orbitals of butadiene and hexatriene g) Expect stereochemical product of electrocyclyic reactions h) Distinguish pathways conratatory and disrotatory i) Distinguish pathways suprafacial and antrafacial
