fotolüüs
Fotolüüs is a term that appears to be a misspelling or a non-standard term. The closest commonly recognized term with a similar sound and potential meaning is "photolysis." Photolysis refers to a chemical process where a molecule is broken down by photons. This is a fundamental process in chemistry and biology, often initiated by light energy. For example, in the Earth's atmosphere, photolysis plays a role in the destruction of ozone molecules by ultraviolet radiation. In biological systems, photosynthesis itself is a complex series of photolytic reactions where light energy is used to convert carbon dioxide and water into glucose and oxygen. The energy from light is absorbed by pigments, which then drives chemical reactions to split water molecules and facilitate the synthesis of organic compounds. Without photolysis, many natural cycles and biological processes would not occur. The specific context in which "fotolüüs" was encountered would be helpful in determining if it has a specialized meaning beyond the general concept of photolysis. If "fotolüüs" refers to a specific application or a different phenomenon, further clarification is needed.
