We have exposed clean and oxygen-precovered Cu(110) surfaces to acetic acid to create adsorbed acetate. Our studies show the formation of a variety of ordered acetate structures depending on the initial oxygen exposure. We have observed the restructuring of step edges and the formation of ordered arrays of up-down steps. Using a purposeful coadsorption strategy, we have obtained images that assist us in developing models for the acetate structures. Fast Fourier transform infrared spectra have been obtained and Hartree-Fock calculations are included for comparison. (C) 2002 Published by Elsevier Science B.V.
