Orbital energy shifts associated with chemical bonding of organic molecules on ZnO nonpolar surfaces
Abstract
Ultraviolet photoemission studies show that adsorption of organic molecules on semiconducting ZnO surfaces produces: (i) bonding shifts of molecular energy levels which indicate chemisorption via π and lone-pair orbitals; and (ii) nearly uniform extramolecular relaxation/polarization shifts of the adsorbate valence orbital energies. © 1976.
