Title:
Surface Oxidation of Supported, Size-Selected Silver Clusters 
Abstract:
We use surface second harmonic generation spectroscopy to study the oxidation of supported, size-selected silver clusters under ultra-high vacuum conditions. The oxidation reaction of small silver clusters between Ag9 and Ag55 is monitored by means of their localized surface plasmon resonance. We observe a rapid decline of the SH-intensity, as soon as cluster samples are exposed to an oxygen partial pressure of 5E-6 mbar, which is attributed to the formation of silver–oxygen-bonds. The evolu...    »
