Abstract

The fullerenes are of considerable theoretical and experimental interest indicating numerous optical and electrical properties with many important potential technological applications. The transfer and withdrawal of electrons from the neutral species of C₇₀ results in redistribution of charges, modifications of multiplicities, electronic energy levels and their band gaps. We use semi-empirical and ab initio methods to investigate the energy levels and stability of C₇₀ as a function of charge and multiplicity.

Keywords: Fullerenes, C₇₀, stability.
