Terahertz spectroscopy of NO and isotopic invariant fit of several nitric oxide isotopologs
Holger S. P. Müller, Kaori Kobayashi, Kazumasa Takahashi +2
A tunable far-infrared laser sideband spectrometer was used to investigate a nitric oxide sample enriched in 18O between 0.99 and 4.75 THz. Regular, electric dipole transitions wer…
Detection of a branched alkyl molecule in the interstellar medium: iso-propyl cyanide
Arnaud Belloche, Robin T. Garrod, Holger S. P. Müller +1
The largest non-cyclic molecules detected in the interstellar medium (ISM) are organic with a straight-chain carbon backbone. We report an interstellar detection of a branched alky…
Revised spectroscopic parameters of SH from ALMA and IRAM 30 m observations
Holger S. P. Müller, Javier R. Goicoechea, José Cernicharo +6
Hydrides represent the first steps of interstellar chemistry. Sulfanylium (SH), in particular, is a key tracer of energetic processes. We used ALMA and the IRAM 30 m telescope…
Laboratory spectroscopy of 1,2-propanediol at millimeter and submillimeter wavelengths
J. -B. Bossa, M. H. Ordu, H. S. P. Müller +2
Ethanediol is one of the largest complex organic molecules detected in space thus far. It has been found in different types of molecular clouds. The two propanediol isomers are the…
Upper limits to interstellar NH+ and para-NH2- abundances. Herschel-HIFI observations towards Sgr B2 (M) and G10.6-0.4 (W31C)
C. M. Persson, M. Hajigholi, G. E. Hassel +12
The understanding of interstellar nitrogen chemistry has improved significantly with recent results from the Herschel Space Observatory. To set even better constraints, we report h…
Millimeter Wave and Terahertz Spectra and Global Fit of Torsion-Rotation Transitions in the Ground, First and Second Excited Torsional States of 13CH3OH Methanol
Li-Hong Xu, R. M. Lees, Yun Hao +5
Methanol is observed in a wide range of astrophysical sources throughout the universe, and comprehensive databases of the millimeter and THz spectra of CH3OH and its principal isot…
