Iodine-Monofluoride (If) Emission Spectrum and Formation Kinetics in Electron Beam Produced Plasmas

Electron beam excitation of argon/CF(,3)I/NF(,3) gas mixtures produces intense blue-green fluorescence attributed to the heteronuclear interhalogen iodine-monofluoride (IF). Analysis of the observed IF emission spectrum has shown that it is most likely due to E (--->) A('3)(PI)(,1) transitions of this molecule. Fluorescence decay measurements indicate that the I('*)(('4)P) species is the IF('*)(E) precursor, and that the observed fluorescence decay rates are controlled by deactivation of this excited iodine species. Collisional deactivation rate coefficients of I('*)(('4)P) by argon, xenon, CF(,3)I, NF(,3), and UF(,6) were measured and are reported.
