Photodissociation of ozone
WebPhotodissociation of ozone (O3) can be described as producing an oxygen atom with heat of formation 247.5 kJ/mol. However, in reality photodissociation yields an oxygen atom that is temporarily in an excited state (O*) with a standard enthalpy of 438 kJ/mol. What maximum wavelength could cause this.

WebNov 8, 1997 · We present time-dependent wave-packet calculations describing the photodissociation of ozone in the Chappuis band, which evolves in the two lowest states of 1A′′ symmetry. The calculations are performed in the diabatic representation and include the coupling between the two relevant states. All three nuclear degrees of freedom are taken … WebIn ozone layer: Ozone creation and destruction This process, called photodissociation, results in the release of single oxygen atoms, which later join with intact oxygen …
WebNov 19, 2012 · We present new calculations of the branching ratios between the various electronic and isotopic photodissociation channels of ozone. Special emphasis is placed on the isotopic/isotopologue differences because the contribution of the ozone photodissociation to the oxygen isotope and ozone isotopologue enrichments or … Photolysis occurs in the atmosphere as part of a series of reactions by which primary pollutants such as hydrocarbons and nitrogen oxides react to form secondary pollutants such as peroxyacyl nitrates. See Photochemical smog. The two most important photodissociation reactions in the troposphere are firstly: which generates an excited oxygen atom which can react with water to give the hydroxyl radical:
