Fotochimie
Fotochimie is the branch of chemistry concerned with the chemical effects of light. It studies the interaction of electromagnetic radiation, particularly ultraviolet and visible light, with matter, leading to chemical changes. The fundamental principle of fotochimie is that a chemical reaction can be initiated by the absorption of a photon of light. This absorbed energy can excite molecules, making them more reactive and enabling them to undergo transformations that might not occur under thermal conditions alone.
Key processes in fotochimie include photoexcitation, where a molecule absorbs a photon and moves to a higher
Fotochimie has significant applications in various fields. In nature, it is crucial for processes like photosynthesis,
