Photodissociation of ozone at 248 nm and vacuum ultraviolet laser-induced fluorescence detection of O(1D)

Abstract

Ozone molecules, O3, were photodissociated in the presence of N2 at 248 nm (KrF laser) to O(1D)+ O2(1Δ). The O(1D) atoms were detected by generating vacuum ultraviolet laser-induced fluorescence (VUV LIF) for the 3s1D0-2p1D transition at 115.2 nm. The 115.2 nm probe laser was generated by frequency tripling (ωVUV = 3ω) of the 345.6 nm PTP dye laser in a Xe gas cell. © 1998 OPA (Overseas Publishers Association) N.V.
