We propose to study the effects of high gas pressures of carbon monoxide on platinum (111) samples at gas pressures in the range 10^-10 mbar to atmosphere. A c(4x2) structure is known to occur after exposure to about 10 Langmuirs of CO, whilst at higher pressures STM measurements indicate the presence of an incommensurate layer. Synchrotron beamtime has been confirmed for this study through the direct access route for novel research (award 37083). In order to ensure that this beamtime is effective, preliminary investigations must be made in order to clean the sample and study the quality of the surface before and after CO exposure. This will be achieved using low energy electron diffraction and Auger Electron Spectroscopy measurements. The X-ray measurements will identify the structures but will also confirm that such measurements are possible on systems at higher pressures. This technique is therefore able to bridge the 'pressure gap' that exists between ultrahigh vacuum research and real conditions in catalytic reaction vessels.
