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 $…
The salty emission of the intermediate-mass AGB star OH 30.1 -0.7
T. Danilovich, A. M. S. Richards, M. Van de Sande +17
We analyse continuum and molecular emission, observed with ALMA, from the dust-enshrouded intermediate-mass AGB star OH 30.1 -0.7. We find a secondary peak in the continuum maps, "…
Millimeter-millimeter-wave double-modulation double-resonance spectroscopy
Oliver Zingsheim, Luis Bonah, Frank Lewen +3
A new millimeter- to millimeter-wave double-modulation double-resonance (MMW-MMW DM-DR) scheme has been applied to record spectra of two astronomically relevant complex organic mol…
Investigation of the rotational spectrum of CHOH and its tentative detection toward Sagittarius B2(N)
Holger S. P. Müller, Vadim V. Ilyushin, Arnaud Belloche +2
Methanol is an abundant molecule in space. The column density of CHOH is in some star-forming regions so high that the search for CHOH is promising. But only very…
Rotational spectroscopy of CHOD with a reanalysis of CHOD toward IRAS 162932422
V. V. Ilyushin, H. S. P. Müller, M. N. Drozdovskaya +10
We have started a measurement campaign of numerous methanol isotopologs in low-lying torsional states in order to provide extensive line lists for radio astronomical observations f…
