Abstract

The adsorption of cinchonidine (CD) on Pt(111) has been investigated by means of STM in the presence and absence of hydrogen. The time-resolved studies revealed that the mobility of adsorbed CD molecules depends on the hydrogen pressure. At low hydrogen pressure the CD molecules are rather immobile, whereas considerable mobility is observed at higher hydrogen pressure. Based on the different adsorption geometries and the surface mobility three different species could be distinguished and their dynamic behaviour was investigated on a single molecule level.
