The mid-infrared molecular inventory towards Orion IRc2
Sarah Nickerson, Naseem Rangwala, Sean W. J. Colgan +8
We present the first high spectral resolution mid-infrared survey in the Orion BN/KL region, covering 7.2 to 28.3 micron. With SOFIA/EXES we target the enigmatic source Orion IRc2.…
The First Mid-Infrared Detection of HNC in the Interstellar Medium: Probing the Extreme Environment Towards the Orion Hot Core
Sarah Nickerson, Naseem Rangwala, Sean Colgan +7
We present the first mid-infrared (MIR) detections of HNC and H13CN in the interstellar medium, and numerous, resolved HCN rovibrational transitions. Our observations span 12.8 to…
The Need for Laboratory Measurements and Ab Initio Studies to Aid Understanding of Exoplanetary Atmospheres
Jonathan J. Fortney, Tyler D. Robinson, Shawn Domagal-Goldman +85
We are now on a clear trajectory for improvements in exoplanet observations that will revolutionize our ability to characterize their atmospheric structure, composition, and circul…
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…
High Spectral Resolution SOFIA/EXES Observations of C2H2 towards Orion-IRc2
Naseem Rangwala, Sean W. J. Colgan, Romane Le Gal +8
We present high-spectral resolution observations from 12.96 - 13.33 microns towards Orion IRc2 using the mid-infrared spectrograph, EXES, on SOFIA. These observations probe the phy…
High-resolution IR absorption spectroscopy of polycyclic aromatic hydrocarbons in the 3 μm region: Role of periphery
Elena Maltseva, Annemieke Petrignani, Alessandra Candian +5
In this work we report on high-resolution IR absorption studies that provide a detailed view on how the peripheral structure of irregular polycyclic aromatic hydrocarbons (PAHs) af…
ExoMol molecular line lists - XIV: The rotation-vibration spectrum of hot SO
Daniel S. Underwood, Jonathan Tennyson, Sergei N. Yurchenko +5
Sulphur dioxide is well-known in the atmospheres of planets and satellites, where its presence is often associated with volcanism, and in circumstellar envelopes of young and evolv…
High-resolution IR absorption spectroscopy of polycyclic aromatic hydrocarbons: the realm of anharmonicity
Elena Maltseva, Annemieke Petrignani, Alessandra Candian +6
We report on an experimental and theoretical investigation of the importance of anharmonicity in the 3 micron CH stretching region of Polycyclic Aromatic Hydrocarbon (PAH) molecule…
High-Accuracy Quartic Force Field Calculations for the Spectroscopic Constants and Vibrational Frequencies of 1 ^1A' l-C3H-: A Possible Link to Lines Observed in the Horsehead Nebula PDR
Ryan C. Fortenberry, Xinchuan Huang, T. Daniel Crawford +1
It has been shown that rotational lines observed in the Horsehead nebula PDR are probably not caused by l-C3H+, as was originally suggested. In the search for viable alternative ca…
Spectroscopic Constants and Vibrational Frequencies for l-C3H+ and Isotopologues from Highly-Accurate Quartic Force Fields: The Detection of l-C3H+ in the Horsehead Nebula PDR Questioned
Xinchuan Huang, Ryan C. Fortenberry, Timothy J. Lee
Very recently, molecular rotational transitions observed in the photon-dominated region of the Horsehead nebula have been attributed to l-C3H+. In an effort to corroborate this fin…
Accurate ab initio anharmonic force field and heat of formation for silane, SiH_4
Jan M. L. Martin, Kim K. Baldridge, Timothy J. Lee
From large basis set coupled cluster calculations and a minor empirical adjustment, an anharmonic force field for silane has been derived that is consistently of spectroscopic qual…
