A tunable diode laser was used to probe the concentration and translational temperature of I atoms produced by F and Cl atom reactions with HI.Kinetic modeling codes were used to determine the discharge efficiencies from the titration plots and the observed trends for atom concentration as a function of F2 or C12 and pressure.These calculations indicated that the DC discharge used in these experiments is 100% efficient for F2 flow rates <= 0.5 mmol/s and reactor pressure <= 20 Torr.The highest F2-free F atom flow rate that we can generate is 1.0 mmol/s.Preliminary data for the C12 discharge indiate that this is a much less efficient source of C1 atoms with yields of less than 50%. The production of F and Cl atoms in an electrical discharge of F 2 or C1 2 has been examined in a flow reactor. A tunable diode laser was used to probe the concentration and translational temperature of I atoms produced by F and Cl atom reactions with HI. Kinetic modeling codes were used to determine the discharge efficiencies from the titration plots and the observed trends for atom concentration as a function of F 2 or Cl 2 and pressure. These calculations indicate that the dc discharge used in these experiments is 100% efficient for F 2 flow rates <0.5 mmol s-1 and reactor pressure 520 torr. The highest F 2 -free F atom flow rate that we can generate is 1.0 mmol s-1. Preliminary data for the C1 2 discharge indicate that this is a much less efficient source of Cl atoms with yields of less than 50%.
