Matches in DBpedia 2016-04 for { ?s ?p "Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible light (400 - 750 nm) or infrared radiation (750 - 2500 nm).Photochemical reactions are valuable in organic and inorganic chemistry because they proceed differently than thermal reactions. Many thermal reactions have a photochemical counterpart. Photochemical paths offer an advantage over thermal methods of forming thermodynamically disfavored products, thereby overcoming large activation barriers in a short period of time, and allowing reactions otherwise inaccessible by thermal processes.Everyday examples include photosynthesis, the degradation of plastics or the formation of vitamin D with sunlight."@en }
