Abstract:

This work has been concerned with the development and use of the digital ESDIAD method for studying the molecular structure and the dynamics of adsorbates on metal single crystal surfaces. A number of new findings have been made involving the following phenomena A First direct observation of the hindered rotation of a chemisorbed molecule B Observation of hydrogen bonding forces between adsorbates causing hinderance of molecular rotation C structural determination of bonding site for coordinatively unsaturated radical species, PF2 and PF on Ni111. D Discovery of alkali metal sensitization of H ESD yield on metals E Discovery of copious metastable CO yield in ESD from CO on Pt111.
