Abstract

At very low CO coverages on Pt(110)-(1 x 2) at 30 K, two C-O stretch infrared bands are observed. Warming to > 40 K results in the loss of the high-frequency band and growth of the low-frequency band. Further warming to greater than or equal to 60 K reverses this process. This reversal is attributed to a thermodynamic transition between 1D islands, or chains, of CO molecules and a 1D gas. The process at greater than or equal to 40 K is attributed to the onset of surface diffusion, when chain condensation occurs from the adsorbate randomly formed at 30 K. (C) 1998 Elsevier Science B.V.
