质量分辨共振多光子电离(MPI)光谱已被用来识别和表征脉冲超音速辉光放电源中产生的瞬变物种。振动热的(直到v‘=9)，但转动冷的一氧化氮的特征是通过A2Σ+态的(1+1)mpi和通过C2Πr态的(2+1)mpi。观察到了9个A←X和6个C←X热带；其中只有4个以前被表征过。意外重叠的C和A态热带可以用不同阶次的MPI格式分别研究。文中还讨论了对之前几项研究的影响。此外，3P0，2亚稳稀有气体原子很容易形成并被MPI检测到，就像从电极上溅射的金属原子一样。
Mass‐resolved, resonant multiphoton ionization (MPI) spectroscopy has been used to identify and characterize transient species produced in a pulsed, supersonic glow discharge source. Vibrationally hot (up to v‘=9), but rotationally cold nitric oxide is characterized by (1+1) MPI via the A 2Σ+ state and (2+1) MPI through the C 2Πr state. Nine A←X and six C←X hot bands are observed; only four of these have been previously characterized. Accidentally overlapping C and A state hot bands can be separately studied by using different order MPI schemes. Implications for several previous studies are discussed. Additionally, the 3P0,2 metastable rare gas atoms are readily formed and detected by MPI as are metal atoms sputtered from the electrodes.
