             "Symmetry and Jahn-Teller effect in fullerene-based materials"


        Abstract: Highly symmetric platonic formations can be realized based 
on
        carbon, as the icosahedral fullerene or the cubic cubane and their
        combinations. This talk will focus on the distortions of such systems
        caused by crystal field, electron-phonon interactions and chemical
        modification. The method of choice is vibrational spectroscopy, as
        vibrational structures are highly sensitive to symmetry. I will show 
examples 
        of static and dynamic Jahn-Teller effect, symmetry changes on doping 
and on 
        polymerization.
