The chemisorbed state of benzene on Si(100)-(2 1) has been studied using a cluster model and semi-empirical PM3 calculations. Starting from four different initial sites as the possible adsorption sites, the most stable structure is obtained as the adsorption at the pedestal site, where one benzene molecule interacts with two silicon dimers of the surface. This stable adsorption of benzene on the...
The species formed by the anodic oxidation of ethyl xanthate at gold electrodes has been investigated using an ex situ Fourier transform infrared (FTIR) spectroscopic technique to distinguish between chemisorbed ethyl xanthate and diethyl dixanthogen. Chemisorption of xanthate was found to commence about 0.15 V below the potential at which dixanthogen deposits and to reach a fractional surface coverage...
