The photolysis of diazoacetylchymotrypsin
WebbThe photolysis of ozone at A = 254 nm has been studied in a time-resolved flow system using helium, argon and nitrogen as carrier gases. Radiation of the O2(1Ag - g ) system at A = 1.27 ym was the only detectable optical emission from the photolysis products. Kinetic studies established directly that O2(1Ag) is a primary product of ozone ... WebbPhotodissociation, 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.
