Exploring molecular complexity with ALMA (EMoCA): Alkanethiols and alkanols in Sagittarius B2(N2)
H. S. P. Müller, A. Belloche, L. -H. Xu +7
Over the past five decades, radio astronomy has shown that molecular complexity is a natural outcome of interstellar chemistry, in particular in star forming regions. However, the…
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…
Exploring Molecular Complexity with ALMA (EMoCA): Deuterated complex organic molecules in Sagittarius B2(N2)
A. Belloche, H. S. P. Müller, R. T. Garrod +1
Deuteration is a powerful tracer of the history of the cold prestellar phase in star forming regions. Apart from methanol, little is known about deuterium fractionation of complex…
A study of the CH isomers and isotopologues: first interstellar detection of HDCCC
S. Spezzano, H. Gupta, S. Brünken +8
The partially deuterated linear isomer HDCCC of the ubiquitous cyclic carbene (-CH) was observed in the starless cores TMC-1C and L1544 at 96.9 GHz, and a confirming lin…
Velocity-resolved [CII] emission and [CII]/FIR Mapping along Orion with Herschel
J. R. Goicoechea, D. Teyssier, M. Etxaluze +22
We present the first 7.5'x11.5' velocity-resolved map of the [CII]158um line toward the Orion molecular cloud-1 (OMC-1) taken with the Herschel/HIFI instrument. In combination with…
Rotational spectroscopy as a tool to investigate interactions between vibrational polyads in symmetric top molecules: low-lying states of methyl cyanide, CHCN
Holger S. P. Müller, Linda R. Brown, Brian J. Drouin +6
Spectra of methyl cyanide were recorded to analyze interactions in low-lying vibrational states and to construct line lists for radio astronomical observations as well as for infra…
