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…
Rovibrational Overtone and Combination Bands of the HCNH+ Ion
Miroslava Kassayová, Miguel Jiménez-Redondo, János Sarka +4
Spectra of vibrational overtone and combination bands from vibrational ground state of HCNH+ were measured using an action spectroscopy technique with active background suppression…
Cl+ and HCl+ in Reaction with H2 and Isotopologues: A Glance into H Abstraction and Indirect Exchange at Astrophysical Conditions
Miguel Jiménez-Redondo, Olli Sipilä, Robin Dahl +2
Astrochemical models of interstellar clouds, the sites of stars, and planet formation require information about spin-state chemistry to allow quantitative comparison with spectrosc…
Ion-kinetic-energy sampling in a 22-pole trap using ring-electrode evaporation
Miguel Jiménez-Redondo, Dieter Gerlich, Paola Caselli +1
We present an experimental method for the characterization of the kinetic energies of ions confined in a 22-pole radio frequency trap by inducing a small potential barrier using th…
