| Abstract: | The interaction of dimethylsulfoxide (DMSO) with a Au(100) surface was studied by means of TDS, XPS and ΔΦ measurements. At monolayer coverages, DMSO desorbs from two states situated at the relatively high temperatures of 240 and 275 K. The adsorbed molecule, however, shows no chemical shifts in its core levels. This is rationalized by a bidentate bonding of DMSO to the surface through the electron lone-pairs on the O and S atoms. The adsorption geometry agrees also with the behavior of the work function (ΔΦDMSO = − 770 meV). |
