Abstract
High resolution photoemission spectroscopy using sub-micron beams of soft X-rays is used to probe in situ prepared cysteine/Pt{1 1 1} surfaces. Cysteine is found to adsorb intact in its zwitterionic form and only its thiol group is observed to bond with surface Pt. The bright beams of light used in these experiments eventually reduce the sulphur-bonded cysteine molecule to a sulphur-bonded CxHy type-molecule. In order to minimise local damage fast scanning is required when imaging using the scanning photoemission microprobe. © 2005 Elsevier
