摘要

We report the production of gaseous hydronitrogen chemical species in a continuous-flow microwave plasma discharge excited in hydrazine (N_2H_4) gas in helium. Products were analyzed by Li~+ ion attachment mass spectrometry. Plasma composition was investigated as a function of N_2H_4/He composition and microwaveinduced power input. A variety of neutral and ionic products were formed and identified mass spectrometrically. The mass spectral analysis revealed the presence of various cluster compounds of N_2H_4, H_2O, and/or NH_3 as well as their ionized species. These cluster compounds were formed by condensation reaction processes. In addition, the interesting neutral hydronitrogen species N_3H_5 and N_4H_6 were tentatively assigned. No species with these chemical formulas are listed in the NIST database. Formation of N_3H_5 and N_4H_6 may involve rearrangement reactions.
