โฆ Synopsis
Rovibrational spectra of Hz, HN:, and H30+ generated in discharge jet-expansion have been studied using a differencefrequency infrared source, The rotational temperatures were determined to be 120 i 20,273 + 20 and 150 -f: 20 K for H: , HN$ , and HsO+, respectively. Some dynamic phenomena of the jet-discharges are also discussed.
