Aromaticity under star dust conditions

Abstract

Astronomical observations have revealed diffuse interstellar bands ranging from blue in the visible spectrum to the near IR. It has been suggested that these bands exist, owing to the presence of polyaromatic hydrocarbons or fullerene in the vicinity of certain stars, and constitute residual material from stellar explosions. The intention here is to study the relative stability of these species, when exposed to extreme conditions. The aromaticity of polycarbon molecules is an important aspect of this explanation.
