Abstract
The adsorption of CO on Pd(111) has been studied with scanning tunneling mi croscopy in the very low coverage regime. Isolated CO molecules were imaged with two different corrugations of similar to 0.25 Angstrom and similar to 0.15 Angstrom, which are attributed to adsorption of the hcp and fee hollo w sites. Total energy calculations reveal that these two sites are the most favorable ones. Calculated image profiles using the ESQC method agree well with the experimental corrugations.
