First detection of C2H+ in the interstellar medium
Arshia M. Jacob, Karl M. Menten, Sandra Brünken +10
Despite the detection of nearly 350 molecules in the interstellar medium, almost half of which are carbon chains, the pathways that build molecular complexity remain poorly underst…
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 p…
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…
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.…
