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 ...

Transformations of organic compounds that are a consequence of that compound's own light absorption are called direct photolysis. The rates of these light-initiated reactions are determined by two factors: (a) the compound's rate of light absorption and (b) the quantum yield for reaction of the excited state.

WebbPhotolysis of hydrogen peroxide in the absence of hydrogen provided the acti-nometer. At sufficiently low peroxide concentration and/or sufficiently high light intensity the photolysis is a non-chain reaction (6) with an over-all limiting quantum yield for peroxide removal of unity (8, 9). The primary quantum yield is one-half the over-all yield.

It causes one of its electrons to move to a higher energy state. The excited electron is transferred to an acceptor molecule and is replaced by an electron from water (H 2 O). It causes the decomposition of water into H + and OH –, hence termed as photolysis.
