Abstract
The electron-phonon and Coulomb interactions in and larger fullerene spheres are analyzed. The coupling between electrons and intramolecular vibrations give corrections ∼1–10 meV to the electronic energies for , and scales as in larger molecules, where R is the radius of the fullerene sphere. The energies associated with electrostatic interactions are of order ∼1–4 eV in and scale as . Charged fullerenes show enhanced electron-phonon coupling, ∼10 meV, which scales as . Finally, it is argued that not only , but also are highly polarizable molecules. The polarizabilities scale as and , respectively. The role of this large polarizability in mediating intermolecular interactions is also discussed.
