Zusammenfassung:RECENT developments in the synthesis of macroscopic amounts of the C60 and C70 carbon clusters have made possible spectroscopic studies of these species. Infrared and vibrational Raman spectra strongly support the proposed 'soccer ball' structure for the C60 cluster, and NMR spectroscopy directly confirms its icosahedral symmetry. Here we present images of C60 clusters obtained with the scanning tunnelling microscope. These species are roughly spherical and form mobile hexagonal arrays on a Au(111) surface with an intercluster spacing of 11.0 Å. Brighter features evident in the arrays are tentatively identified as C70 clusters.
