Thermodynamic Properties of Rocket Combustion Products.
Abstract
The matrix isolation technique has been used to obtain the optical spectra of some high temperature species which are formed when aluminum is combusted in the presence of oxygen and hydrogen. Specifically, a search has been for the species Al2O3(g), AlO2(g) and AlHO(g), in the vaporization products of aluminum oxide at high temperature, either by itself, or in the presence of O2(g) or H2O(g). Of the above species, there was some evidence for the existence of AlO2(g), based on oxygen isotopic studies, but no definitive evidence was obtained for Al2O3(g) or AlHO(g). The species Al2O(g) was identified as a major vaporization product of aluminum oxide. The previously estimated bending frequency of this molecule at 240/cm was shown to be in error. A new bending frequency of 120 plus or minus 30/cm was estimated by analogy with Li2O. Evidence was obtained for the presence of the species O, Al, AlO and Al2O2 in the vapors over molten aluminum oxide in addition to Al2O and AlO2, noted above. (Author)
