CO adsorption on Cu(100) has been found to be completely reversible over the temperature range 77–300°K and pco=10−8−10−4 torr using LEED and work function measurements. The isosteric heat has been determined as a function of coverage, and strong correlations have been found with surface structural changes. An in-registry→out-of-registry transition was observed at 0.5 monolayer suggesting once again that localization on high coordination substrate sites may not be so important as commonly believed.
