Abstract :
The adsorption of CO on Pt(111) has been studied with variable temperature scanning tunnelling microscopy (STM). The well-known c(4×2)–CO structure formed at saturation has been used as a test system for the determination of molecular adsorption sites in an overlayer structure from comparison between theoretical and experimental STM images. By calculating the STM images of the c(4×2)–CO structure with CO placed in different adsorption sites on the surface, only the structure with CO in on-top and bridge sites agrees with the experimental images.
