Abstract

The spectrum of electron-hole excitations in carbon nanoclusters is calculated using the simple Frenkel-exciton model Hamiltonian, which includes a dipole-dipole interaction between electron-hole chargeless excitations. The nearest-neighbor approximation is used for simplicity, though the generalizations for the full dipole interaction is straightforward. The group-theoretical approach gives the exact results for some mode frequencies, as well as wavevectors of excitations.
