Image analysis of low-energy electron diffraction (LEED) intensity vs. voltage (IV) curves was used to analyze the surface geometries of amines and alcohols adsorbed on the Si(100)-2x1 surface. Clean silicon and ammonia-covered surfaces were used as calibration systems. The data from these surfaces compare well within experimental uncertainties. Results to be presented include the dimethylamine, trimethylamine and ethanol-covered surfaces. These results will be compared to computational treatments of probable reaction pathways of these adsorbates on silicon using the cluster models of the surface. Also to be presented will be comparisons of results for these reactions from slab models of the surface.
