Abstract : The objectives of this project were to study a variety of main group compounds and their reactions, with special emphasis on the chemistry of silicon and how the behavior of this element relates to problems of Air Force interest. The process investigated included the detailed mechanism of the chemical vapor deposition (CVD) process, the polymerization mechanism of silanols, the role of hypervalent silicon in polymerization mechanisms, and the relationship of hypervalent silicon to hypervalent aluminum. Toward the end of the project, the effort broadened into investigations of the interactions of silicon with transition metals, in view of the role of the transition metals as catalysts in a variety of reactions. The second main area of investigation has been the design and study of high energy content molecules, with the intent of designing new potentially higher energy fuels. One compound that had been previously proposed by others, the asymmetric dimer of NO, was shown by us to predissociate. So, this compound will not be a realistic HEDM compound. We think, however, that other isomers of the NO dimer have greater potential for new fuels, and these possibilities will be explored.
