INTRODUCTION Comets and asteroids preserve information on the earliest stages of Solar
System formation and on the composition of its building blocks. The nature of their solid …

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. High-quality vibrational spectra of solid-phase molecules in ice mixtures and for
temperatures of astrophysical relevance are needed to interpret infrared observations …

Context. Small imines containing up to three carbon atoms are present in the interstellar
medium (ISM). As alkynyl compounds are abundant in this medium, propargylimine (2 …

Complex organic molecules are widely observed in star-forming regions, although their
formation mechanisms are not well understood. Solid-state chemistry is thought to play an …

Studying the chemical composition of organic matter in astrophysical environments is an
important means to improve our understanding of its origin and evolution. This organic …

Context. Hydroxylamine (NH 2 OH) and methylamine (CH 3 NH 2) have both been
suggested as precursors to the formation of amino acids and are therefore, of interest to …

We conducted survey observations of a glycine precursor, methanimine, or methylenimine
(CH 2 NH), with the Nobeyama Radio Observatory 45 m telescope and the Sub-Millimeter …

The modelling of molecular excitation and dissociation processes relevant to astrochemistry
requires the validation of theories by comparison with data generated from laboratory …

Context. In the search for the building blocks of life, nitrogen-bearing molecules are of
particular interest since nitrogen-containing bonds are essential for the linking of amino …
