Studies of Excited Hydrogen in Relation to Advanced Propulsion.
Abstract
The formation and disappearance of vibrationally excited hydrogen molecules are being investigated in fast-flowing streams of discharge-excited hydrogen. Excited H2 is monitored by observations of vibrational energy transfer to HCN, which then emits 3-micron infrared radiation. In addition, an automated isothermal calorimeter has been built for catalytic thermal detection of the energetic species. Preliminary calorimetric results indicate that atoms and excited molecules can be distinguished by performing experiments at different flow rates. Hydrogen atoms are also monitored independently by their chemiluminescent reaction with NO. (Author)
