PHOTODISSOCIATION OF OZONE AT 248 NM AND VACUUM-ULTRAVIOLET LASER-INDUCED FLUORESCENCE DETECTION OF O(D-1)

Ozone molecules, O-3, were photodissociated in the presence of N-2 at 248 nm (KrF laser) to O(D-1) + O-2((1)Delta). The O(D-1) atoms were de tected by generating vacuum ultraviolet laser-induced fluorescence (VU V LIF) for the 3s(1)D(0)-2p(1)D transition at 115.2 nm. The 115.2 nm p robe laser was generated by frequency tripling (omega(VUV) = 3 omega) of the 345.6 nm PTP dye laser in a Xe gas cell.
