Photochemistry

Subject: Chemistry

Book: General Chemistry

Photochemistry studies chemical reactions triggered by light (photons). Absorption of photons excites electrons, initiating processes like photosynthesis or photolysis. Applications include UV curing of polymers, light-driven synthesis, and understanding atmospheric reactions (ozone formation/destruction). Photochemistry lies at the heart of solar energy conversion, fueling research on photovoltaic materials and artificial photosynthesis.
