In particular, emission and laser-induced-fluorescence studies of CH produced by direct-electron-impact dissociation reveal the postdissociation kinetics of CH as well as a means of estimating the CH density. In a 20-Torr 10%∕20%∕70% mixture of argon/methane/nitrogen, the instantaneous CH density is determined to be 2.1×1013cm−3 at the end of the steady-state voltage and current condition. Kinetics analysis reveals that neutral chemistry with methane is the largest loss process for the CH fragments. Analysis of N2(C-B) rotational temperatures indicates that less than 30% of the input electrical energy is deposited as heat in the gas, with the balance going toward dissociation, excitation of internal molecular states, and ionization.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670318878430209","@type":"Researcher","foaf:name":[{"@value":"Michael S.
