Notes:
The absorption spectrum of the special C60 cluster buckminsterfullerene has been studied in a supersonic beam by laser depletion of the cold van der Waals complexes of C60 with benzene and methylene chloride. Both complexes were found to display a single, isolated absorption band in the near ultraviolet superimposed on a structureless absorption continuum. For the methylene chloride complex this feature is centered at 3860 A(ring), and is roughly 50 cm−1 wide. In the benzene van der Waals cluster, the corresponding feature is located at 3863 A(ring), and has a similar width. This spectrum is tentatively assigned to the 0–0 band of the lowest 1T1u←1Ag (LUMO+1←HOMO) transition of a truncated icosahedral carbon shell structure, broadened by coupling to the underlying quasicontinuum of ground state vibrational levels.
