INVESTIGATIONS OF THE IMINO RADICALS IN THE SHOCK TUBE PYROLYSIS OF N2H4, NH3, ND3 AND SHOCK TUBE STUDIES ON N20 AND NH3 AT HIGH PRESSURES,

Abstract

An optical arrangement was set up which allows simultaneous recording of the decompositions of various species of the nitrogen-hydrogen system on the basis of light absorption in the ultraviolet. Parent molecules investigated in this way were N2H4 and ND3. Even during fast decompositions of N2H4 the amounts of NH are appreciably less than those appearing during NH3 pyrolysis. Comparing NH or ND absorption traces during the decompositions of NH3 and ND3, resp. indicates similar decomposition mechanisms even though the rate constants of the parent molecules show appreciable differences. In addition, the approach of the high-pressure limit in the unimolecular decomposition of NH3 and N2O was investigated by means of the high-pressure shock tube described previously. (Author)
