氮（N2）第二正系统的振转光谱带拟合是一种用于估计N2放电或添加微量N2的原子放电的中性气体温度的技术。对于涉及氩和N2的混合物，氩亚稳原子（Ar*）和N2分子之间的共振能量转移可能影响使用第二正系统进行的气体温度估计。Ar* 共振能量转移的效果进行了研究，在这里通过分析中性气体温度的氩-N2的混合物，为N2的百分比从1%到100%。中性气体的温度估计高于预期的混合物，涉及大于5%的N2添加，但氩气与小于5%的N2添加时，与离子中性电荷交换碰撞加热的分析模型相比是合理的。额外的时空调查中性气体温度估计与10%N2添加表明，虽然绝对温度值可能会受到Ar* 共振能量转移，时空趋势仍然可以用来准确地诊断放电。
Rovibrational spectroscopy band fitting of the nitrogen (N2) second positive system is a technique used to estimate the neutral gas temperature of N2discharges, or atomic discharges with trace amounts of a N2 added. For mixtures involving argon and N2, resonant energy transfer between argon metastable atoms (Ar*) and N2 molecules may affect gas temperature estimates made using the second positive system. The effect of Ar* resonance energy transfer is investigated here by analyzing neutral gas temperatures of argon-N2 mixtures, for N2 percentages from 1% to 100%. Neutral gas temperature estimates are higher than expected for mixtures involving greater than 5% N2 addition, but are reasonable for argon with less than 5% N2 addition when compared with an analytic model for ion-neutral charge exchange collisional heating. Additional spatiotemporal investigations into neutral gas temperature estimates with 10% N2 addition demonstrate that although absolute temperature values may be affected by Ar* resonant energy transfer, spatiotemporal trends may still be used to accurately diagnose the discharge.
