We present theoretical results on the electronic excitations and optical properties of small fullerenes, namely C24, C28, C32 and C36. Quasiparticle-corrected HOMO-LUMO gaps have been computed through the ∆SCF scheme. Photoabsorption spectra have been obtained in the framework of time-dependent density-functional theory. Calibration calculations per- 4formed for C20 and C60 result in good agreement with the available experimental and theoretical data.

Abstract
We present theoretical results on the electronic excitations and optical properties of small fullerenes, namely C24, C28, C32 and C36. Quasiparticle-corrected HOMO-LUMO gaps have been computed through the ∆SCF scheme. Photoabsorption spectra have been obtained in the framework of time-dependent density-functional theory. Calibration calculations per- 4formed for C20 and C60 result in good agreement with the available experimental and theoretical data.
