photolysisBreakdown of molecules into smaller units via absorption of light. Flash photolysis, an experimental technique developed by Manfred Eigen, Ronald George Weyford Norrish, and George Porter, studies short-lived chemical intermediates formed in many photochemical reactions. An intense, brief flash of light splits molecules into short-lived fragments, which are analyzed by spectrophotometry in a second, less intense flash. photolysis [fō′täl·ə·səs] (physical chemistry) The use of radiant energy to produce chemical changes.

| QIAquick 96 PCR purification cartridges (Qiagen, Hilden, Germany, with modified binding and wash buffers) were used to remove unincorporated primers before tags were decoupled from amplification products by UV photolysis in a flow cell and analyzed in a quadrapole mass spectrometer by using positive-mode atmospheric pressure chemical ionization (APCI-MS, Agilent Technologies, Palo Alto, CA, USA). For this analysis, maximum application rates were used for each insecticide, and each estimated concentration was then applied to the model above, using the surface photolysis half-life to estimate the rate of degradation. Molecular oxygen undergoes photolysis to give oxygen atoms, which in the presence of an inert body (M) reacts with more oxygen to give ozone. |
