Spatially Resolved Optical Emission Spectroscopy Measurements within a Single Microdischarge of a Dielectric Barrier Discharge

and have been measured within a single microdischarge for a surface, discharge-mode dielectric barrier discharge (SDBD), using optical emission spectroscopy. The reduced electric field was determined indirectly and resolved spatially within a single microdischarge. It is shown that the vibrational temperature profile, within a microdischarge, is at a maximum along the outer edges, decreasing to a minimum in the center. The rotational temperature of was found to have the same profile within a microdischarge; however, the rotational temperature of was found to be at a minimum along the outer edges, increasing to a maximum in the center. The reduced electric field was shown to be at a maximum along the outer edges, decreasing to a minimum at the center of a cathode spot which suggests that the outer edge of the microdischarge, during the negative voltage half- cycle, is a type of sheath where the electric field is at a maximum. Rotational temperatures of and were shown to be nearly identical during the positive voltage half- cycle; however, deviated significantly during the negative voltage half-cycle. During the negative voltage half-cycle, the rotational temperature of ranged from 800 to
