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…
Millimeter and submillimeter spectroscopy of methylallene, CHCHCCH
Holger S. P. Müller, Frank Lewen, Jean-Claude Guillemin +1
Small polycyclic aromatic hydrocarbons and somewhat larger cyano derivatives were detected in the cold dark cloud TMC-1 recently. Their formation from smaller hydrocarbons is not w…
Rotational Spectroscopy as a Tool to Study Vibration-Rotation Interaction: Investigations of CHCN and CHCN up to and a Search for Transitions toward Sagittarius B2(N)
Holger S. P. Müller, Arnaud Belloche, Frank Lewen +1
Methyl cyanide, CHCN, is present in diverse regions in space, in particular in the warm parts of star-forming regions where it is a common molecule. Rotational transitions of $…
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…
Submillimeter-wave spectroscopy of the CHO radical
Jean-Thibaut Spaniol, Olivia Chitarra, Olivier Pirali +2
The methoxy radical, CHO, has long been studied experimentally and theoretically by spectroscopists because it displays a weak Jahn-Teller effect in its electronic ground state…
