The aromatic universe
TLDR
In this paper, the vibrational and electronic spectra of polycyclic aromatic hydrocarbons and their fullerene derivatives are analyzed. But the analysis is limited to planar flakes of fused benzene rings.Abstract:
The rich molecular structures of polycyclic aromatic hydrocarbons—essentially planar flakes of fused benzene rings—and their fullerene cousins are revealed through their vibrational and electronic spectra.read more

Spectroscopy of polycyclic aromatic hydrocarbons and very small grains in photodissociation regions
TL;DR: In this article, a singular value decomposition method with a Monte Carlo search algorithm was used to analyse the mid-infrared ISOCAM spectral maps of photodissociation regions (PDRs) in NGC-7023 and ρ Oph-SR3.

Carbon-rich dust past the asymptotic giant branch: aliphatics, aromatics, and fullerenes in the Magellanic Clouds
Gregory C. Sloan,Eric Lagadec,Albert A. Zijlstra,Kathleen E. Kraemer,A. P. Weis,A. P. Weis,Mikako Matsuura,Kevin Volk,Els Peeters,Els Peeters,Walter W. Duley,Jan Cami,Jan Cami,Jeronimo Bernard-Salas,Francisca Kemper,Raghvendra Sahai +15 more
TL;DR: In this paper, the position and width of the feature at 18.7-18.9 um and other features at 17.4 and 6-9 um were used to test for the presence of fullerenes.

Radiative cooling of size-selected gas phase clusters
TL;DR: In this article, the radiation from thermally populated excited electronic states has been recognized as an important cooling mechanism in free molecules and clusters, and it has been used as a cooling mechanism for free molecules.

Superhydrogenation of pentacene: the reactivity of zigzag-edges
Dario Campisi,Frederik Doktor S Simonsen,J. D. Thrower,Rijutha Jaganathan,Liv Hornekær,Rocco Martinazzo,Alexander G. G. M. Tielens +6 more
TL;DR: This work has investigated the structural stability and activation energy barriers for the superhydrogenation of pentacene using Density Functional Theory, and revealed a preferential hydrogenation pattern set by theactivation energy barriers of the hydrogenation steps.

Detection of C60 and C70 in a Young Planetary Nebula
Jan Cami,Jan Cami,Jeronimo Bernard-Salas,Jeronimo Bernard-Salas,Els Peeters,Els Peeters,Sarah E. Malek +6 more
TL;DR: The environment of Tc 1, a peculiar planetary nebula whose infrared spectrum shows emission from cold and neutral C60 and C70, is studied, indicating that if the conditions are right, fullerenes can and do form efficiently in space.

Laboratory confirmation of C60+ as the carrier of two diffuse interstellar bands
TL;DR: Maier et al. as discussed by the authors reported laboratory spectroscopy of C60+ in the gas phase, cooled to 5.8 kelvin, and confirmed that the diffuse interstellar bands that Foing and Ehrenfreund observed do arise from C60 molecules in the interstellar medium.
