▪ Abstract Our understanding of the evolution of organic molecules, and their voyage from
molecular clouds to the early solar system and Earth, has changed dramatically …

Diffuse interstellar clouds have long been thought to be relatively devoid of molecules,
because of their low densities and high radiation fields. However, in the past ten years or so …

A critical review of the very long-standing problem of the diffuse interstellar bands is
presented with emphasis on spectroscopic aspects of observational, modelling and …

We establish correlations between equivalent widths of eight diffuse interstellar bands
(DIBs), and examine their correlations with atomic hydrogen, molecular hydrogen, and EB …

In 2019 it was exactly 100 years ago that the first two DIBs, diffuse interstellar bands, were
discovered by Mary Lea Heger. Today some 500+ DIBs are known. In numerous …

The interstellar gas and the gas ejected into space by cool stars are now known to contain a
rich collection of molecules. Most of these are organic compounds, some of which are …

Seventy-seven reactive organic molecules of astrophysical interest have been identified in a
supersonic molecular beam, 73 in the radio band by Fourier-transform microwave …

Context. The identification of the carriers of the diffuse interstellar bands (DIBs) is the longest
standing problem in the study of the interstellar medium. Here we present recent UV …

The carriers of the diffuse interstellar bands (DIBs) are largely unidentified molecules
ubiquitously present in the interstellar medium (ISM). After decades of study, two strong and …

The photon induced fragmentation behavior of the cations of three dibenzopyrene (C 24 H
14) isomers (DBPae, DBPah and DBPal) is studied in a series of systematic mass …
