Description
The reaction of trim ethyl aluminum, Al(CHJ)J, and HNJ was experimentally studied in the lab by low temperature matrix isolation. The reactants, each diluted to 1% in argon, were deposited at selected stoichiometric ratios onto a potassium chloride salt window at approximately lO K. Low temperature matrix isolation eliminated the reaction of the reactants and products with the walls of the reaction vessel. FTIR was used to monitor the presence of chemical species, the reactants and new azide containing species, in the solid argon matrix. Goals of the low temperature matrix isolation study was to observe new species being formed by the appearance of features in the FfIR spectrum that were unique to the reactants and to confirm the identity of the species. Comparison of frequencies to be calculated for likely candidates of products and comparison of the chemical shifts of the products' azide asymmetric stretch from the N3 asymmetric stretch of HN3 with the frequencies and chemical shifts observed in the FTIR spectrum will be used to identify products.
