Orientation of Chemical Bonds at Surfaces: A Key to Understanding the Structure and Bonding of Surface Species

摘要

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 Ni(111). (D) Discovery of alkali metal sensitization of H+ ESD yield on metals; (E) Discovery of copious metastable CO yield in ESD from CO on Pt(111). (jes)
