Abstract
Microwave discharges through gases containing poisonous chemical agents are of interest because of the possibility of using such discharges in air purification systems, in this work the radical PO was detected downstream from such a discharge through simulants of chemical agents. Laser-ex- cited fluorescence (LEF) of the PO radical was obtained by pumping in the B2Σ+ ←X2 π 3250-Å system. Franck-Condon vibrational overlap factors (FCF), which are necessary for the quantitative de- termination of the radical in absorption or fluorescence experiments, were measured for the √ = 0 progression. Although the chemical agents are very dangerous, the simulants in this work are quite safe and are to be preferred as PO precursors to the poisonous materials used in earlier studies. 1-4
