New laboratory techniques using heterodyne receivers
Nadine Wehres, Kirill Borisov, Katharina von Schoeler +4
Two laboratory emission spectrometers have been designed and described previously. Here, we present a follow-up study with special focus on absolute intensity calibration of the ne…
100 GHz Room-Temperature Laboratory Emission Spectrometer
Nadine Wehres, Bettina Heyne, Frank Lewen +6
We present first results of a new heterodyne spectrometer dedicated to high-resolution spectroscopy of molecules of astrophysical importance. The spectrometer, based on a roomtempe…
Laboratory spectroscopic study and astronomical detection of vibrationally excited n-propyl cyanide
Holger S. P. Müller, Adam Walters, Nadine Wehres +8
We performed a spectral line survey called Exploring Molecular Complexity with ALMA (EMoCA) toward Sagittarius~B2(N) between 84.1 and 114.4 GHz with the Atacama Large Millimeter/su…
Rotational spectra of isotopic species of methyl cyanide, CHCN, in their excited vibrational states
H. S. P. Müller, B. J. Drouin, J. C. Pearson +3
Methyl cyanide is an important trace molecule in space, especially in star-forming regions where it is one of the more common molecules used to derive kinetic temperatures. We want…
A coincidence between a hydrocarbon plasma absorption spectrum and the lambda 5450 DIB
H. Linnartz, N. Wehres, H. Van Winckel +5
The aim of this work is to link the broad lambda 5450 diffuse interstellar band (DIB) to a laboratory spectrum recorded through an expanding acetylene plasma. Cavity ring-down dire…
