Infrared Spectroscopy of Pentagon-Containing PAHs: Indenyl and Fluorenyl Anions and Indenyl Cation
Gabi Wenzel, Miguel Jiménez-Redondo, Milan Ončák +4
Polycyclic aromatic hydrocarbon (PAH) ions are crucial intermediates in interstellar chemistry and may play a key role in the infrared emission features observed in space. Here, we…
PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar
Ryan Chown, Ameek Sidhu, Els Peeters +136
(Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs ar…
Infrared action spectroscopy as tool for probing gas-phase dynamics: Protonated Dimethyl Ether, (CH)OH, formed by the reaction of CHOH with CHOH
Vincent Richardson, Daniel B. Rap, Sandra Brünken +1
Methanol is one of the most abundant interstellar Complex Organic Molecules (iCOMs) and it represents a major building block for the synthesis of increasingly complex oxygen-contai…
Resonant infrared irradiation of CO and CH3OH interstellar ices
J. C. Santos, K. -J. Chuang, J. G. M. Schrauwen +6
Solid-phase photo-processes involving icy dust grains greatly affect the chemical evolution of the interstellar medium by leading to the formation of complex organic molecules and…
Buckyball-metal complexes as promising carriers of astronomical unidentified infrared emission bands
Gao-Lei Hou, Olga V. Lushchikova, Joost M. Bakker +3
Infrared emission bands with wavelengths between 3-20 μm are observed in a variety of astrophysical environments [1,2]. They were discovered in the 1970s and are generally attribut…
Deuteration of c-CH towards the pre-stellar core L1544
K. Giers, S. Spezzano, F. Alves +7
Context: In the centre of pre-stellar cores, the deuterium fractionation is enhanced due to the cold temperatures and high densities. Therefore, the chemistry of deuterated molecul…
Top-down formation of ethylene from fragmentation of superhydrogenated polycyclic aromatic hydrocarbons
Zeyuan Tang, Frederik Doktor S. Simonsen, Rijutha Jaganathan +4
Fragmentation is an important decay mechanism for polycyclic aromatic hydrocarbons (PAHs) under harsh interstellar conditions and represents a possible formation pathway for small…
PDRs4All: A JWST Early Release Science Program on radiative feedback from massive stars
Olivier Berné, Émilie Habart, Els Peeters +134
Massive stars disrupt their natal molecular cloud material through radiative and mechanical feedback processes. These processes have profound effects on the evolution of interstell…
Infrared action spectroscopy of doubly charged PAHs and their contribution to the aromatic infrared bands
Shreyak Banhatti, Julianna Palotás, Pavol Jusko +4
The so-called aromatic infrared bands are attributed to emission of polycyclic aromatic hydrocarbons. The observed variations toward different regions in space are believed to be c…
Hunting for the elusive methylene radical
A. M. Jacob, K. M. Menten, Y. Gong +4
CH2 transitions between 68 and 71 GHz were first detected toward the Orion-KL and W51 Main SFRs. Given their upper level energies of 225 K, they were thought to arise in dense, hot…
Structural investigation of doubly-dehydrogenated pyrene cations
Sanjana Panchagnula, Jordy Bouwman, Daniël B. Rap +7
The vibrationally resolved spectra of the pyrene cation and doubly-dehydrogenated pyrene cation (CH; Py and CH; ddPy) are presented…
Breakdown products of gaseous polycyclic aromatic hydrocarbons investigated with infrared ion spectroscopy
A. Petrignani, M. Vala, J. R. Eyler +5
We report on a common fragment ion formed during the electron-ionization-induced fragmentation of three different three-ring polycyclic aromatic hydrocarbons (PAHs), fluorene (C$_{…
Anharmonicity in the mid-infrared spectra of polycyclic aromatic hydrocarbons: Molecular beam spectroscopy and calculations
A. K. Lemmens, D. B. Rap, J. M. M. Thunnissen +5
Aims. In this work we determine the effects of anharmonicity on the mid-infrared spectra of the linear polycyclic aromatic hydrocarbons (PAHs) naphthalene, anthracene, tetracene an…
