Query: Electronic interactions in fullerene spheres   The electron-phonon and Coulomb interactions inC$_{60}$, and larger fullerene
spheres are analyzed. The coupling between electrons and intramolecular
vibrations give corrections $\sim 1 - 10$ meV to the electronic energies for
C$_{60}$, and scales as $R^{-4}$ in larger molecules. The energies associated
with electrostatic interactions are of order $\sim 1 - 4$ eV, in C$_{60}$ and
scale as $R^{-1}$. Charged fullerenes show enhanced electron-phonon coupling,
$\sim 10$ 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 $R^4$, respectively. The role of this large
polarizability in mediating intermolecular interactions is also discussed.
