High-resolution ro-vibrational and rotational spectroscopy of the open-shell, linear CCH ion ()
Kim Steenbakkers, Weslley G. D. P. Silva, Oskar Asvany +5
In this work, we report on the high-resolution infrared spectrum of CCH () recorded in the range ~cm by means of leak-out spectroscopy. This spectral ran…
Experimental proof of strong - mixing in the Renner-Teller and Pseudo-Jahn-Teller affected CCH () ion
Kim Steenbakkers, P. Bryan Changala, Weslley G. D. P. Silva +8
The ethynyl radical cation, CCH (), offers a unique system for fundamental spectroscopic studies of non-adiabatic effects due to its open-shell linear structure and the pr…
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…
Multi-Orbital Charge Transfer into Nonplanar Cycloarenes Revealed with CO-Functionalized Tips
Anja Haags, Alexander Reichmann, Zilin Ruan +20
On-surface synthesis has allowed for the tuneable preparation of numerous molecular systems with variable properties. Recently, we demonstrated the highly selective synthesis of ke…
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…
