flash photolysis
Quick Summary
Flash photolysis is a chemical process used to study short-lived chemical intermediates. It involves exposing a substance to an intense, brief flash of light, which breaks down molecules into smaller fragments. A second, less intense flash then helps identify these fragments using spectrophotometry.12
Developed by R.G.W. Norrish and George Porter in 1949, this technique is crucial for understanding the mechanisms of fast chemical reactions by identifying transient species. It allows scientists to observe and analyze reactions that occur too quickly for traditional methods.13

…used the new technique of flash photolysis to study the intermediate stages involved in extremely rapid chemical reactions. In this technique, a gaseous system in a state of equilibrium is subjected to an ultrashort burst of light that causes photochemical reactions in the gas. A second burst of light is…
