Millimeter and submillimeter spectroscopy of the deuterated molecular ion SD+

Autor: Araki, Mitsunori, Lattanzi, Valerio, Endres, Christian P., Caselli, Paula

Seven rotational and fine-structure transitions of the deuterated molecular ion SD+ in the X 3S- ground electronic state have been measured in the 271-863 GHz region in the laboratory. This ion has been produced by DC-glow discharge using a mixture o

High-resolution gas phase spectroscopy of molecules desorbed from an ice surface: a proof-of-principle study

Autor: Theulé, Patrice, Endres, Christian, Hermanns, Marius, Bossa, Jean-Baptiste, Potapov, Alexey

High-resolution gas phase spectroscopy techniques in the microwave, millimeter-wave and terahertz spectral ranges can be used to study complex organic molecules desorbed from interstellar ice analogues surface with a high sensitivity. High-resolution

100 GHz Room-Temperature Laboratory Emission Spectrometer

Autor: Wehres, Nadine, Heyne, Bettina, Lewen, Frank, Hermanns, Marius, Schmidt, Bernhard, Endres, Christian, Graf, Urs U., Higgins, Daniel R., Schlemmer, Stephan

We present first results of a new heterodyne spectrometer dedicated to high-resolution spectroscopy of molecules of astrophysical importance. The spectrometer, based on a roomtemperature heterodyne receiver, is sensitive to frequencies between 75 and

Accurate sub-millimetre rest-frequencies for HOCO$^+$ and DOCO$^+$ ions

Autor: Bizzocchi, Luca, Lattanzi, Valerio, Laas, Jacob, Spezzano, Silvia, Giuliano, Barbara Michela, Prudenzano, Domenico, Endres, Christian, Sipilä, Olli, Caselli, Paola

Publikováno v: A&A 602, A34 (2017)

HOCO$^+$ is a polar molecule that represents a useful proxy for its parent molecule CO$_2$, which is not directly observable in the cold interstellar medium. This cation has been detected towards several lines of sight, including massive star forming

Publikováno v: J. Mol. Spectrosc. 327 (2016) 95-104

The CDMS was founded 1998 to provide in its catalog section line lists of molecular species which may be observed in various astronomical sources using radio astronomy. The line lists contain transition frequencies with qualified accuracies, intensit

Report

Dimethyl ether in its ground state, v=0, and lowest two torsionally excited states, v11=1 and v15=1, in the high-mass star-forming region G327.3-0.6

Autor: Bisschop, Suzanne E., Schilke, Peter, Wyrowski, Friedrich, Belloche, Arnaud, Brinch, Christian, Endres, Christian P., Güsten, Rolf, Hafok, Heiko, Heyminck, Stefan, Jørgensen, Jes K., Müller, Holger S. P., Menten, Karl M., Rolffs, Rainer, Schlemmer, Stephan

Publikováno v: Astron. Astrophys. 552 (2013), A122

The goal of this paper is to determine the respective importance of solid state vs. gas phase reactions for the formation of dimethyl ether. This is done by a detailed analysis of the excitation properties of the ground state and the torsionally exci
