Abstract

The room-temperature rate constants for quenching of I* ( ⁴P) atoms in binary collisions with Ar, Xe, NF₃, UF ₆, and CF₃I have been measured to be ≲2×10 ^-13, (8.3±0.5)×10^-11, (2.6±0.5) ×10^-11, (5.8±0.4)×10^-10, and (3.8±0.4)×10^-10 cm³ sec^-1, respectively. These constants were obtained by examining the exponential time decay of the IF (D′→A′) fluorescence in the afterglow of electron beam produced plasmas containing Ar, CF₃I, NF₃, and the desired quenching gas. Also, further experimental evidence in support of neutral channel formation of IF* via quenching of I* ( ⁴P) states by fluorine containing molecules in e-beam-pumped Ar/CF₃I/NF₃ mixtures is presented.
