Introduction to photochemistry, Study notes of Organic Chemistry

These notes provides a foundational understanding of photochemistry, the study of chemical reactions induced by light. Students will explore the essential principles that govern how molecules absorb light energy, undergo electronic transitions, and initiate chemical transformations. This course covers fundamental concepts, including absorption of light, electronic excitation, photophysical processes, and the difference between singlet and triplet states. Core topics include quantum yields, photochemical kinetics, and common photochemical reactions. Emphasis will be placed on photophysical processes such as fluorescence, phosphorescence, and intersystem crossing.
