Absorption spectroscopy of AlO including photodissociation

open access: yes
Photodissociation of AlO may be important for the aluminium chemistry in various astrophysical regions. The photodissociation cross sections and rates of AlO were investigated over the temperature range from 0 to 15000 K in this work.

Charge Resonance Interaction in Aromatic Trimer Radical Cations Revealed by IR Spectroscopy: The Case of Pyrrole Homo‐ and Heterotrimers

open access: yesChemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
We demonstrate the power of high‐resolution infrared spectroscopy and complementary quantum chemical calculations to unravel the evolution of the aromatic charge resonance interaction (CR) in cold trimer radical cations for the prototypical pyrrole clusters.

Non-Equilibrium Photodissociation Regions: Ionization-Dissociation Fronts

open access: yes, 2007
We discuss the theory of coupled ionization--dissociation fronts produced when molecular clouds are exposed to ! 1110 A radiation from hot stars. A steady, composite structure is developed, which generally includes an ionized outflow away from the cloud,

Magnetic Field Alignment Relative to Multiple Tracers in the High-mass Star-forming Region RCW 36

open access: yesThe Astrophysical Journal
We use polarization data from SOFIA HAWC+ to investigate the interplay between magnetic fields and stellar feedback in altering gas dynamics within the high-mass star-forming region RCW 36, located in Vela C.

Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle

open access: yesChemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

Non-equilibrium photodissociation regions: ionization-dissociation fronts

open access: yes, 1995
We discuss the theory of coupled ionization-dissociation fronts produced when molecular clouds are exposed to #lambda# < 1110Aa radiation from hot stars. A steady, composite structure is developed, which generally includes an ionized outflow away from

Vacuum Ultraviolet Single Photon Ionization and Decomposition of 2-Aminopropionitrile in Astrophysical Objects

open access: yesThe Astrophysical Journal
The molecule 2-aminopropionitrile (2-APN; H _3 CCH(NH _2 )CN) is a chiral precursor of the amino acid alanine and could play an important role in the emergence of the homochirality of life.

Uncaging Iridium(III) Complexes for Combined Photodynamic and Photoactivated Chemotherapy

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 41, 5 October 2026.
Light‐activatable iridium(III) anticancer prodrugs demonstrate how chalcogen coordination controls photoinduced therapeutic activity. Upon visible‐light irradiation, sulfur‐ and selenium‐based caging ligands undergo distinct oxygen‐dependent photoreactions that trigger ligand release and singlet oxygen generation, enabling combined photoactivated ...
