Hyperfine-Resolved Rovibrational and Rotational Spectroscopy of OH ()
Weslley G. D. P. Silva, Lea Schneider, Urs U. Graf +6
The OH () radical cation has been investigated by combining a 4 K 22-pole ion trap apparatus with high-resolution IR and THz radiation sources. Applying different typ…
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 ra…
Broadband infrared spectroscopy of methanol isotopologues in pure, H2O-rich, and CO-rich ice analogues
Adam Vyjidak, Barbara Michela Giuliano, Pavol Jusko +5
Deuterium fractionation is highly efficient during the early stages of star formation, particularly in starless and prestellar cores where temperatures are low (<10 K) and molecula…
High Resolution Overtone Spectroscopy of HNC and HCN
Miguel Jiménez-Redondo, Chiara Schleif, Julianna Palotás +5
Rotationally resolved spectra of the HNC and HCN molecular ions have been recorded in the spectral range between 6200 and 6800 \rcm\ using a cryogenic ion trap instrument.…
Near-infrared high resolution overtone spectroscopy of the hydronium ion HO: the and bands
Chiara Schleif, Hayley A. Bunn, Miguel Jiménez-Redondo +2
This work presents the rovibrational spectra of the two strongest first overtone bands of the asymmetric stretching mode ( and ) of the hydronium ion…
Infrared Spectroscopy of Pentagon-Containing PAHs: Indenyl and Fluorenyl Anions and Indenyl Cation
Gabi Wenzel, Miguel Jiménez-Redondo, Milan OnÄák +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…
