Abstract
Ozone molecules, O3, were photodissociated in the presence of N2 at 248 nm (KrF laser) to O(1D)+ O2(1∆). The O(1D) atoms were detected by generating vacuum ultraviolet laser-induced fluorescence (VUV LIF) for the 3s1D0 -2p 1D transition at 115.2 nm. The 115.2 nm probe laser was generated by frequency tripling (ω vuv=3ω) of the 345.6 nm PTP dye laser in a Xe gas cell.

Our planet Earth’s atmosphere is a big photochemical reactor, in which the light source is the Sun
The O(D) atoms were detected by generating vacuum ultraviolet laser-induced fluorescence (VUV LIF) for the 3sD-2pD transition at l15.2nm
Chemical processes in the stratosphere are intimately connected with the phenomenon of the ozone layer in the 15-45km altitude regime
Summary
Our planet Earth’s atmosphere is a big photochemical reactor, in which the light source is the Sun. The O(D) atoms were detected by generating vacuum ultraviolet laser-induced fluorescence (VUV LIF) for the 3sD-2pD transition at l15.2nm. Keywords." Ozone; O(D); tripling in Xe; vacuum ultraviolet laser-induced fluorescence; Doppler profile
