WebMar 7, 2024 · Ozone vapor, O 3, is here visualized in a gliding arc discharge using photofragmentation laser-induced fluorescence.Ozone is imaged by first photodissociating the O 3 molecule into an O radical and a vibrationally hot O 2 fragment by a pump photon. Thereafter, the vibrationally excited O 2 molecule absorbs a second (probe) photon that … An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma; the plasma may produce visible light. An arc discharge is initiated either by thermionic emission or by field emission. After initiation, the arc relies on thermionic emission of electrons from the electrodes supporting …
