Since neutron scattering has a high sensitivity to hydrogen and an absence of selection rules, it is an ideal technique for investigating hydrogen storage materials. Filter Difference Spectrometer spectra of NH3BH3 (ammonia borane) was collected at 10 K in the near to mid-IR region to elucidate the mechanism for H2 release and uptake as well as further investigate the nature of the non-classical dihydrogen bonding in these solid state hydrogen storage materials. These results were compared to previous Raman and IR experiments as well as theoretical calculations. Adsorption of ammonia borane onto a mesoporous silica substrate reduced the onset of hydrogen release and altered the decomposition products. The interfacial interactions between the ammonia borane and the mesoporous silica led to changes in the solid state properties. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
