XeF* and XeCl* formation in low-pressure tesla coal discharges
The XeCl* and XeF* emission spectra have been studied from mixtures of Xe with HCl, Cl/sub 2/, CCl/sub 4/, NF/sub 3/, BF/sub 3/, C/sub 2/F/sub 6/, and SF/sub 6/ in a tesla-coil-driven discharge. The XeX* emission spectra were recorded at pressures below 0.75 torr for all reagents except BF/sub 3/ and C/sub 2/F/sub 6/, which did not give XeF* emission. Low-pressure pulsed dc discharge experiments in Xe/Cl/sub 2/ and Xe/HCl mixtures gave XeCl* emission spectra very similar to those observed from the tesla-driven discharge. Computer simulations of the XeCl(B-X) spectra from discharges of Xe with Cl/sub 2/, CCl/sub 4/, and HCl provide an estimate for the XeCl(B) vibrational distributions. Since Xe(/sup 3/P/sub 2/) and Xe(/sup 2/P/sub 1/) reacting with HCl and SF/sub 6/ do not give XeX*, the observation of XeX* from these two reagents requires the reactions of Xe Rydberg states or recombination of Xe/sup +/ and Cl/sup -/ or F/sup -/ ions. Arguments based upon XeCl* and XeF* vibrational and electronic state populations and the time dependence of the emission suggest that Rydberg state reactions are the dominant mechanism contributing to the XeX* excitation from the low-pressure discharge of Xe/HCl and Xe/SF/sub 6/ mixtures.
