Electronic Interactions in Fullerene Spheres. Typeset Using Revtex

The electron-phonon and Coulomb interactions inC60, and larger fullerene spheres are analyzed. The coupling between electrons and intramolecular vibrations give corrections ∼ 1 − 10 meV to the electronic energies for C60, and scales as R −4 in larger molecules. The energies associated with electrostatic interactions are of order ∼ 1 − 4 eV, in C60 and scale as R −1. Charged fullerenes show enhanced electronphonon coupling, ∼ 10 meV, which scales as R−2. Finally, it is argued that non only C−60, but also C −− 60 are highly polarizable molecules. The polarizabilities scale as R 3 and R4, respectively. The role of this large polarizability in mediating intermolecular interactions is also discussed.
