Spectroscopic Detection and Characterization of Cyanooxomethylium, NCCO
Marcel Bast, Julian Böing, Thomas Salomon +6
Cyanooxomethylium, NCCO, a fundamental linear acylium ion, has been observed spectroscopically for the first time using action spectroscopy in ion trap apparatuses. A first low…
High-Resolution Infrared Spectroscopy and ASAP Analysis of Cyclopentadiene: The Vibrational Modes below 860 cm and the Mode at 961 cm
Luis Bonah, Marie-Aline Martin-Drumel, Olivier Pirali +9
The spectroscopic fingerprints of vibrationally excited states of astronomical molecules are interesting for multiple reasons. They are excellent temperature probes of the correspo…
A quest for sulfur-bearing refractory species. Identification of CaS in the interstellar medium
A. Tasa-Chaveli, Ã. Sánchez-Monge, A. Fuente +10
The recent detection of refractory molecules in massive star-forming regions provides a means of probing the innermost regions of disks around massive stars. These detections also…
Leveraging MMW-MMW Double Resonance Spectroscopy to Understand the Pure Rotational Spectrum of Glycidaldehyde and 17 of Its Vibrationally Excited States
Luis Bonah, Jean-Claude Guillemin, Arnaud Belloche +3
Broadband measurements of glycidaldehyde in the frequency ranges 75-170 and 500-750 GHz were recorded to extend previous analyses of its pure rotational spectrum in the microwave r…
Extending the rotational spectrum of cyclopentadiene towards higher frequencies and vibrational states
Luis Bonah, Benedikt Helmstaedter, Jean-Claude Guillemin +2
Cyclopentadiene (c-C5H6) is a cyclic pure hydrocarbon that was already detected astronomically towards the prototypical dark cloud TMC-1 (Cernicharo et al. 2021, Astron. Astrophys.…
