Abstract: This is the second progress report on the work performed at Sandia Corporation in the use of spectrographic techniques in plasmajet diagnostics. Typical results of spectrographic data from argon and nitrogen plasmajets are included. For the argon jet, the results from line intensity measurements of ionized and unionized atoms generally give good information. However, results from hydrogen line broadening measurements indicate several unexplained discrepancies. For the nitrogen jet, the N2 (0, 0) and N2 (0, 1) bands from the first negative series were used to determine a rotational temperature.
