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 /sup 2/..sigma../sup +/ state and (2+1) MPI through the C /sup 2/Pi/sub r/ state. Nine Aleft-arrowX and six Cleft-arrowX 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 /sup 3/P/sub 0,2/ metastable rare gas atoms are readily formed and detected by MPI as are metal atoms sputtered from the electrodes.
