We develop a scaling relationship between the exciton binding energy and theexternal dielectric function in carbon nanotubes. We show that theelectron-electron and electron-hole interaction energies are strongly affectedby screening yet largely counteract each other, resulting in much smallerchanges in the optical transition energy. The model indicates that the relevantparticle interaction energies are reduced by as much as 50 percent uponscreening by water and that the unscreened electron-electron interaction energyis larger than the unscreened electron-hole interaction energy, in agreementwith explanations of the "ratio problem." We apply the model to measurements ofthe changes in the optical transistion energies in single, suspended carbonnanotubes as the external dielectric environment is altered.
