The attention is paid not only to the description of chemical changes initiated by the excitation but also to the opposite processes - i.e. to the formation of excited states in the course of the chemical reaction. The description of the reaction mechanisms of the concrete photochemical reactions is m entioned but the major portion of the lectures is devoted to the general theoretical introduction to the photochemical and physico-chemical experimental techniques of photochemical processes study. For acquiring the overall survey of photochemical problematic there are involved also selected chapters of free radicals, especially oxygen radicals. There will be also discussed natural photochemical processes, a wide range of applications in technological practice and photodynamic effect (medicinal application). Electrochemical part of the lectures involves the theory of excitation of semi-conductor electrodes and more recent applications of these electrodes - as e.g. Gratzel cell. 1. Formation and deactivation of excited states 2. Transfers of electron excitation energy and extinguishing 3. Theory of photochemical reaction 4. Experimental methods of photochemistry, sources of irradiation, reactors, flesh photolysis 5. Survey of mechanisms of photochemical reactions 6.Reactive forms of oxygen and its reactivity, singlet oxygen, superoxide, peroxide, hydroxyl radical 7. Theory, mechanisms and usage of chemiluminiscent reactions 8.Photochemistry without light 9. Photochemical processes in technical practise, photography, and photolithography processes 10. medicinal and environmental aspects of photochemistry, photosynthesis, degradation of polymers 11. semiconductor electrodes - types, characteristics and photoexcitation of semicondactor electrodes 12.Photchemical processes - water fission, Gratzel cells 13. Electro-generable chemiluminiscence - its usage in physical and analytical practice
