ABOUT THE COURSE: The course is designed to teach the fundamentals of photochemical reactions to cover the postgraduate syllabus of many Indian universities. This course is taught as a core course of the program. Since photochemistry is a prominent area of study in many chemistry fields, most students find it essential to have a basic and advanced understanding of these reactions. The syllabus covers the topics like: Fundamental Principles of Photochemistry, Photochemistry of organic compounds like Alkenes, dienes, carbonyl compounds, aromatic compounds, etc.INTENDED AUDIENCE: MSc ( Chemistry)PREREQUISITES: B.Sc (Chemistry)INDUSTRY SUPPORT: Pharmaceuticals and fine chemical companies
Overview
