Abstract
UV radiation-induced coalescence reaction of C-60 were in situ monitored by Raman spectroscopy for the first time, and the process was also characteri zed by STM and laser desorption mass spectrometry. The Raman measurement re veal that, after the coalescence reaction, the vibration bands correspondin g to the highly symmetric A(g) mode of the C-60 molecules either disappear or become very weak, while the bands from other vibration modes just get br oaden and red-shifted, suggesting that the coalesced products are larger co njugated molecules but with lower symmetry. The STM measurements show the g rowth of the coalesced products which eventually form a film. (C) 1999 Else vier Science B.V. All rights reserved.
