ABSTRACT Our modern day Solar System has 4.6× 109 yr of evolution behind it with just a
few relics of its birth conditions remaining. Comets are thought to be some of the most …

The conformational space of 3-chloropropionic acid has been studied under the isolated
conditions of a supersonic expansion using Stark-modulated free-jet absorption millimeter …

The rotational spectra of a mixture of 2, 4-pentanediol (PDL) isomers, comprising both the
meso isomers [(2R, 4S) and (2S, 4R)] and the racemic isomers [(2R, 4R) and (2S, 4S)], were …

We report a combination of quantum mechanical calculations and a range of spectroscopic
measurements in the gas phase of N, N-diethylhydroxylamine, an important scavenger …

Radio telescopes are used by astronomers to observe the naturally occurring radio waves
generated by planets, interstellar molecular clouds, galaxies, and other cosmic objects …

The rotational spectra of 4′-aminoacetophenone, and those of two conformers (Z and E
arrangement of the CO and NH2 groups) of 3′-aminoacetophenone and their 13C and 15N …

The rotational spectrum of 2′-hydroxyacetophenone has been recorded and assigned for
the first time using a Stark-modulated free-jet absorption millimeter-wave (FJ-AMMW) …

The jet-cooled rotational spectrum of 1, 2-butanedithiol was observed in the frequency
region 2–8 GHz. Two conformers were detected for the molecule, corresponding to anti-and …

Context. Cysteamine (NH 2 CH 2 CH 2 SH), a molecule of potential astrobiological interest,
has not yet been detected in the interstellar medium. Furthermore, the sulfur-stituted isomer …

Radioastronomical observations allowed for the detection of two amides (formamide and
acetamide) and some sulfur-containing molecules (among them, ethanethiol and …
