Doubly ^13^C-substituted ethyl cyanide
We have performed a spectral line survey called Exploring Molecular Complexity with ALMA (EMoCA) toward Sagittarius B2(N) between 84.1 and 114.4GHz with the Atacama Large... -
K-H_2_ line shapes for cool brown dwarfs spectra
Observations of cooler and cooler brown dwarfs show that the contribution from broadening at many bars pressure is becoming important. The opacity in the red optical to near-IR... -
Warm ISM in the Sagittarius A Complex
We investigate the spatial and spectral distribution of the local standard of rest (LSR) velocity resolved submillimetre emission from the warm (25-90K) gas in the Sgr A... -
Rotational spectrum of ^13^C methylamine
Methylamine (CH_3_NH_2_) is a light molecule of astrophysical interest, which has an intensive rotational spectrum that extends in the submillimeter wave range and far beyond,... -
Mono-^13^C acetaldehydes mm/submm wave spectra
The acetaldehyde molecule is ubiquitous in the interstellar medium of our galaxy, and due to its dense and complex spectrum, large dipole moment, and several low-lying torsional... -
Vibrationally excited vinyl cyanide in Orion-KL
Laboratory characterization (18-1893 GHz) and astronomical detection (IRAM-30m: 80-280GHz, Orion-KL) of CH_2_CHCN (vinyl cyanide) in its ground and vibrationally excited states.... -
HCOO^13^CH_3_ rotational spectrum
An astronomical survey of interstellar molecular clouds needs a previous analysis of the spectra in the microwave and sub-mm energy range of organic molecules to be able to... -
THz spectrum of methylamine
Methylamine (CH_3_NH_2_) is the simplest primary alkylamine and has been detected in the interstellar medium. The molecule is relatively light, with the 50K Boltzmann peak... -
^14^N/^15^N isotopic ratio in L1544
Samples of pristine solar system material found in meteorites and interplanetary dust particles are highly enriched in ^15^N. Conspicuous nitrogen isotopic anomalies have also... -
Infra-red transitions of Ca and Mg
While solar spectra contain a lot of CaI and MgI infrared lines, no laboratory-measured spectra of these atoms have been reported for wavenumbers below 2000cm^-1^. This study... -
(Sub)mm spectrum of deuterated methyl cyanides
The study of deuterated abundant molecules is recognized as important in understanding molecular complexity in star-forming regions. We seek to assign the laboratory millimeter... -
CH_2_NH accurate rotational rest frequencies
Methanimine (CH_2_NH) has been detected in different astronomical sources, both galactic (as in several "hot cores", the circumstellar enevolope IRC+10216, and the L183... -
Submillimeter spectrum of HCOOCD_2_H
Astronomical surveys of interstellar molecules, such as those that will be available with the very sensitive ALMA telescope, require preliminary laboratory investigations of the... -
Submm spectrum of deuterated glycolaldehydes
Glycolaldehyde, a sugar-related interstellar prebiotic molecule, has recently been detected in two star-forming regions, Sgr B2(N) and G31.41+0.31. The detection of this new... -
Collisional excitation of sulfur dioxide
We present collisional rate coefficients for SO_2_ with ortho and para molecular hydrogen for the physical conditions prevailing in dark molecular clouds. Rate coefficients for... -
New FeII energy levels from stellar spectra
The spectra of B-type and early A-type stars show numerous unidentified lines in the whole optical range, especially in the 5100-5400{AA} interval. Because FeII transitions to... -
HD 145788, 21 Peg and pi Cet chemical analysis
Modern spectroscopy of early-type stars often aims at studying complex physical phenomena such as stellar pulsation, the peculiarity of the composition of the photosphere,... -
Rotational spectrum of HCOO^13^CH_3_
Laboratory measurements and analysis of the microwave and millimeter-wave spectra of potential interstellar molecules are a prerequisite for their subsequent identification by... -
Low temperature Rosseland opacities
We provide low temperature opacity data that incorporate varied abundances of the elements carbon and nitrogen. In the temperature range that we focus at, molecules are the... -
Oxygen recombination lines from Cas A knots
Fast-moving knots (FMK) in the Galactic supernova remnant Cassiopeia A consist mainly of metals and allow us to study element production in supernovae and to investigate shock...
