(in Polish) Fotochemia i wolne rodniki 0600-S2-CM-FWR

Lecture:
The lecture contains information on the nature of electromagnetic radiation and the interaction of light with matter. Basic concepts and laws of photochemistry, issues related to radiation absorption and excited states of molecules and excited state quenching processes, fluorescence and phosphorescence, Jabłoński diagram, quantum yields, energy and electron transfer processes, reactive oxygen species will be discussed. Examples of photochemical reactions will be presented. The use of photochemistry in medicine.
Lab:
Laboratory exercises are devoted to the detection of singlet oxygen, the study of the influence of UV radiation on the decomposition of dye in the presence and absence of semiconductors, the study of photochromic processes in azo compounds, the study of photochemical transformations of pyrimidine and purine bases, and the study of photosensitization and photostabilization processes.
