Discovery of HCCCH in TMC-1
W. G. D. P. Silva, J. Cernicharo, S. Schlemmer +13
Based on a novel laboratory method, 14 mm-wave lines of the molecular ion HCCCH have been measured in high resolution, and the spectroscopic constants of this asymmetric ro…
Accurate rotational rest frequencies for ammonium ion isotopologues
José-Luis Doménech, Stephan Schlemmer, Oskar asvany
We report rest frequencies for rotational transitions of the deuterated ammonium isotopologues NH3D+, NH2D2+ and NHD3+, measured in a cryogenic ion trap machine. For the symmetric…
First laboratory detection of vibration-rotation transitions of CH and CH and improved measurement of their rotational transition frequencies
José L. Doménech, Pavol Jusko, Stephan Schlemmer +1
The long-searched C-H stretches of the fundamental ions CH and CH have been observed for the first time in the laboratory. For this, the state-dependent attachment o…
Accurate frequency determination of vibration-rotation and rotational transitions of SiH+
José L. Doménech, Stephan Schlemmer, Oskar Asvany
The fundamental 28SiH+ ion has been characterized in a collaborative work, utilizing a hollow-cathode-discharge laser-spectrometer and a cryogenic ion trap spectrometer. Twenty-thr…
Detection of the Ammonium Ion in Space
J. Cernicharo, B. Tercero, A. Fuente +9
We report on the detection of a narrow feature at 262816.73 MHz towards Orion and the cold prestellar core B1-bS, that we attribute to the 1(0)-0(0) line of the deuterated Ammonium…
