- An ozone, O3 , line is photochemically created from molecular oxygen by an ultraviolet ArF excimer laser. After a fixed time delay, the ozone line is imaged with a KrF excimer laser sheet (248 nm) that photodissociates the ozone and produces vibrationally excited O2. — “otv”,
- Hydroxyl tagging velocimetry is a linear method in which an ArF laser, operating at 193 nm wavelength, photodissociates water in a humid flow. In this single-photon process, photodissociation of vibrationally excited H2O creates lines of OH at a concentration higher than the ambient OH. — “Combustion Laser Diagnostics at Vanderbilt University”, vuse.vanderbilt.edu

- Radiation from a photolysis laser, usually operated at 193 nm, photodissociates gaseous molecules, converting them into atomic or small molecular fragments which are intensely fluorescent. If necessary, fluorescence of fragments can be induced by a second, "probe," laser. — “Laser Photolytic Fragmentation-Fluorescence Spectrometry of”,
- Though it is found at all levels in the atmosphere, it is dense near the surface and comes mainly from vehicle exhaust and fuel combustion sources. In the troposphere it photodissociates to give free oxygen atoms, which can produce ground level ozone (smog). — “Nitrogen Dioxide — GES DISC: Goddard Earth Sciences, Data”, disc.sci.gsfc.nasa.gov

- Hydroxyl tagging velocimetry (HTV) is a velocimetry method used in humid air flows. where a 248-nm excimer laser photodissociates the formed O3 and fluoresces the vibrationally excited O2 product thus revealing. — “Hydroxyl tagging velocimetry - Wikipedia, the free encyclopedia”,
- The UV light photodissociates the O3 into neutral O and O2, which are then ionized by the undulator beam. A quadrupole mass spectrometer selects products with one charge-to-mass ratio (e.g., O2 as opposed to O), and an ion detector measures. — “ALSNews Vol. 35 September 5, 1995”, als.lbl.gov

In these studies, a laser pulse photodissociates CO from its active binding site and the ensuing structural. — “2010 SSRL/LCLS Users' Meeting and Worshops”, www-conf.slac.stanford.edu
- HBr, in the stratosphere, ozone is continuously being formed via the Chapman mechanism. However, halogen radicals such as bromine and chlorine (released from Unfortunately, the success of HBr as a reservoir species is very limited due to the fact that it photodissociates quickly and easily. — “hydrogen bromide”,
