Abstract:

The Chemistry Department, University of North Texas, was granted funds from AFOSR in the amount of 50,000 which was applied to the purchase of a Varian Gemini 200 high-field 200 megahertz Fourier transform FT nuclear magnetic resonance NMR spectrometer. This routine instrument, used for observation of 1H and 13C nuclei, has been used continuously since its arrival to improve the efficiency of currently funded DoD research that involves synthesis of new high energyhigh density solid and liquid hydrocarbon fuels, synthesis of new energetic materials, and synthesis of isotopically labeled amines and organoammonium nitrate salts. These projects have received generous financial support from the U. S. Air Force and Army. In addition, the availability of this new NMR instrument has provided expanded opportunities for research on polysilylpolyynes and polysiloxyalkynes that are of interest as potential new semiconductors, photoresists, and ceramic precursors and design and analysis of anionic polymerization initiators for the synthesis of improved elastomers. Finally, the new 200 MHz NMR instrument has provided new opportunities for hands-on experience with high-field NMR for non-NMR spectroscopists, thereby affording important experience for the education and training of future chemists. jg
