The determination from the rotational, vibrational, and excitation temperatures within the AC plasma particles are predominant; is provided by the energy from the populations of those anthe population of rotational statesmany parameters, in the reactor. Figure 7a showsspecies due to the fact this spectrum within the AC plasma reactorsuch as instance of these are affected by these particles. In equilibrium situations, the rotational temperature is deemed an excellent applied AC voltage of 22 kV. Rotational, vibrational, and excitation temperatures have been approximation in the gas temperature (imply kinetic temperature of heavy particles). Alternatively, the population of vibrational and electronic states, with larger energy separation, is offered primarily by collisions with electrons. In this case, the obtained vibrational and excitation temperatures is often considered a closer approximation to the electron temperature.Species 19,Intensity (a.u.)Appl.
