On New Year’s Eve, 2023, Harold Linnartz suddenly passed away at the age of 58. Harold was the head of the Astrophysics Laboratory of Leiden Observatory. He was a highly respected leader in the field of molecular astrophysics—specifically in the areas of molecular spectroscopy and its application to the carriers of the Diffuse Interstellar Bands, in the spectroscopy and reactions of low temperature solids as relevant to interstellar ices, and in the photochemistry of PAHs as they speak to the challenges of the AIBs.

With this Special Issue in ACS Earth and Space Chemistry, we want to honor Harold’s scientific legacy. We welcome articles on all aspects of molecular astrophysics; in particular, those that touch closely on Harold’s scientific interests, which were very broad as, in his scientific career, he focused on unlocking the chemistry of the heavens in the broadest sense.

As a spectroscopist pur sang, shining light on molecules in space was one of his guiding principles. Fathoming the behavior of molecules under the extreme conditions of space was another. Topics that may be covered in the Special Issue may include, but are not limited to:

  • Gas-phase spectroscopy
  • Spectroscopy and dynamics of ices
  • Photo physics of Polycyclic Aromatic Hydrocarbons and related compounds
  • Astronomical observations involving molecules
  • Modeling of astrophysical conditions, planets to galaxies

The deadline for submissions is January 1, 2025.
