Photodissociation, photolysis, photodecomposition, or photofragmentation is a chemical reaction in which molecules of a chemical compound are broken down by photons. It is defined as the interaction of one or more photons with one target molecule. Photodissociation is not limited to visible light. Any … See more Photolysis is part of the light-dependent reaction or light phase or photochemical phase or Hill reaction of photosynthesis. The general reaction of photosynthetic photolysis can be given in terms of photons See more In astrophysics, photodissociation is one of the major processes through which molecules are broken down (but new molecules are being … See more Currently orbiting satellites detect an average of about one gamma-ray burst per day. Because gamma-ray bursts are visible to distances encompassing most of the observable universe, a volume encompassing many billions of galaxies, this suggests that … See more Photoacids are molecules that upon light absorption undergo a proton transfer to form the photobase. In these reactions the dissociation occurs in the electronically … See more Photolysis occurs in the atmosphere as part of a series of reactions by which primary pollutants such as hydrocarbons and nitrogen oxides react to form secondary … See more Single photons in the infrared spectral range usually are not energetic enough for direct photodissociation of molecules. However, after absorption of multiple infrared photons a … See more • Flash photolysis • Photocatalysis • Photochemistry • Photohydrogen See more WebMay 22, 1992 · The principal oxidants in the lower atmosphere are ozone (O 3) and two by-products of O 3 photodissociation, the hydroxyl radical (OH) and hydrogen peroxide (H 2 …

Throughout the history of the atmosphere, sources and sinks have often been simultaneously present. WebAbout 2% of Titan’s atmosphere is methane, which undergoes photodissociation at the alpha-Lyman wavelength (121.6 nm). Methane fragments recombine into heavier organic molecules such as aliphatic and polycyclic aromatic hydrocarbons.
