Fully anharmonic infrared cascade spectra of polycyclic aromatic hydrocarbons
Cameron J. Mackie, Tao Chen, Alessandra Candian +2
The infrared (IR) emission of polycyclic aromatic hydrocarbons (PAHs) permeates our universe; astronomers have detected the IR signatures of PAHs around many interstellar objects.…
Anharmonicity and the infrared emission spectrum of highly excited PAHs
Tao Chen, Cameron Mackie, Alessandra Candian +2
Aims. Infrared (IR) spectroscopy is a powerful tool to study molecules in space. A key issue in such analyses is understanding the effect that temperature and anharmonicity have on…
Laboratory gas-phase infrared spectra of two astronomically relevant PAH cations: diindenoperylene, CH and dicoronylene, CH
Junfeng Zhen, Alessandra Candian, Pablo Castellanos +3
The first gas-phase infrared spectra of two isolated astronomically relevant and large PAH cations - diindenoperylene (DIP) and dicoronylene (DC) - in the 5301800 cm (18.…
Photoinduced polycyclic aromatic hydrocarbon dehydrogenation: Molecular hydrogen formation in dense PDRs
P. Castellanos, A. Candian, H. Andrews +1
The physical and chemical conditions in photodissociation regions (PDRs) are largely determined by the influence of far ultraviolet radiation. Far-UV photons can efficiently dissoc…
High-resolution IR absorption spectroscopy of polycyclic aromatic hydrocarbons in the 3 micron region: role of hydrogenation and alkylation
E. Maltseva, C. J. Mackie, A. Candian +6
Aims. We aim to elucidate the spectral changes in the 3 micron region that result from chemical changes in the molecular periphery of polycyclic aromatic hydrocarbons (PAHs) with e…
