Decomposition reactions of nitroen oxides in direct current glow discharges
Studies were conducted by the Bureau of Mines to determine the positive ions and neutral species produced in glow discharges of gas streams containing 1.0 percent NO in helium, 29 percent dry air in helium, and 1.06 percent NO in N/sub 2/. Mass spectrographic measurements were conducted for gas pressures from 2.3 to 10.0 torr and dc currents from 10 to 20 mA. Ion species observed included NO/sup +/, N/sub 2//sup +/, O/sub 2//sup +/, N/sup +/, and O/sup +/ with lesser amounts of He/sup +/, He/sub 2//sup +/, and NO/sub 2//sup +/. Variations in various ionic and neutral species with discharge duration were interpreted to be consistent with an electrically induced dissociation of NO to produce N/sub 2/ and O/sub 2/. No nitrogen oxides were observed to form in glow discharges of the helium-air mixture.
