The chemistry of the interstellar medium occurs under extreme conditions and can lead to
the formation of exotic molecules. These are species that on Earth are unstable and/or …

Context. Many molecules observed in the interstellar medium are thought to result from the
thermal desorption of ices. Parameters such as the desorption energy and pre-exponential …

Context. Detailed astrochemical models are a key component to interpret the observations of
interstellar and circumstellar molecules since they allow important physical properties of the …

Stellar systems are often formed through the collapse of dense molecular clouds which, in
turn, return copious amounts of atomic and molecular material to the interstellar medium. An …

Context. Substituted methanimines and ethylenes have been identified in the interstellar
medium. Therefore, allylimine (CH 2= CH–CH= NH) represents a promising candidate for a …

Context. The chemical pathways linking the small organic molecules commonly observed in
molecular clouds to the large, complex, polycyclic species long suspected of being carriers …

The reaction between cyano radicals (CN, X2Σ+) and cyanoethene (C2H3CN) has been
investigated by a combined approach coupling crossed molecular beam (CMB) experiments …

Context. The chemical and physical evolution of starless and pre-stellar cores are of
paramount importance to understanding the process of star formation. The Taurus Molecular …

Laboratory studies of the radiation chemistry occurring in astrophysical ices have
demonstrated the dependence of this chemistry on a number of experimental parameters …

We present the first identification in interstellar space of the propargyl radical (CH 2 CCH).
This species was observed in the cold dark cloud TMC-1 using the Yebes 40 m telescope …
