Course objectives
The main objective of the course is making students aware of basic photochemistry and photophysics. The course discusses the chemistry that follows the absorption of electromagnetic radiation. It explains the extraordinary influence of visible or ultraviolet light on structural changes and chemical behaviour of organic compounds. The course covers applied photochemistry; i.e. photochemical applications in the industry, medicine and biology. Common photochemical transformations in nature are also discussed.
