All-carbon atomic rings, cyclo [n] carbons, have recently attracted vivid attention of
experimentalists and theoreticians. Among them, cyclo [18] carbon is the most studied …

Polycyclic aromatic nitrogen heterocycles (PANHs) are present in various astronomical
environments where they are subjected to intense radiation. Their photodissociation …

The systematic analysis of the correlations between diffuse interstellar bands (DIBs) is
extended to weak DIBs through the comprehensive catalogue of the Apache Peak …

Polycyclic aromatic hydrocarbons (PAHs) are abundantly present in the interstellar medium
and in our solar system and lock up a significant fraction of cosmic carbon. They are found to …

Polycyclic aromatic hydrocarbons are an important component of the interstellar medium of
galaxies and photochemistry plays a key role in the evolution of these species in space …

Highly unsaturated carbon chains are generated in combustion processes and electrical
discharges, and are confirmed constituents of the interstellar medium. In hydrogen-rich …

In search of the cause behind the similarities often seen in the fragmentation of PANHs,
vacuum ultraviolet (VUV) photodissociation of two pairs of isomers quinoline–isoquinoline …

Organic compounds, such as the polycyclic aromatic hydrocarbons (PAHs), are among the
major species responsible for the infrared spectral features characterising the cosmic …

Infrared (IR) emission bands by interstellar polycyclic aromatic hydrocarbons (PAHs) and
polycyclic aromatic nitrogen heterocycles (PANHs) are observed towards a large variety of …

The optical absorption spectra of cyclo [n] carbons (n= 10, 14, 18) are investigated in the
framework of time-dependent density functional theory. The collective plasmon excitations …
