IR spectra of cationic 1,5,9-triazacoronene and two of its cationic derivatives
The gas-phase mid-IR spectra of cationic 1,5,9-triazacoronene and two of its cationic derivatives are presented. Their spectra suggest a possible contribution of polycyclic aromatic nitrogen heterocycles to the interstellar aromatic infrared bands.

Controlling achiral and chiral conformations of benzyl alcohol by ortho-halogenation, collisional relaxation and dimerisation
Depending on the carrier gas, ortho-chlorobenzyl alcohol in jet expansions is more or less chiral and hydrogen-bonded.
Paper
Symmetry reduction induced by argon tagging gives access to low-lying excited states of FeH+ in the overtone region of the Fe–H stretching mode
The overtone of the Fe–H stretch in ArFeH+ is observed by argon tagging, but the low-lying electronic transition lights up only in the non-linear Ar2FeH+ species.
Paper
Gold oxide formation on Au(111) under CO oxidation conditions at room temperature
On a Au(111) model catalyst, we observe the formation of gold oxide islands under exposure to atmospheric pressures of oxygen or CO oxidation reaction conditions in an in situ scanning tunneling microscope.
Paper
Simulation of the non-adiabatic dynamics of an enone-Lewis acid complex in an explicit solvent
Lewis acid catalysis is a promising tool in photochemistry. Thus, the ultrafast dynamics of a substrate-Lewis acid complex is investigated in silico, which reveals an intriguing dissociation–reassociation mechanism.
Paper
Moisture changes inside hydrogel particles during their drying process investigated with fluorescence lifetime imaging
Fluorescence lifetime imaging was used to follow the drying process of microgels from their swollen state to their dry state at different air humidities.
About this collection
This themed collection of Physical Chemistry Chemical Physics (PCCP) is devoted to the 123rd Bunsen-Tagung meeting which took place on 25th - 27th March 2024 in Aachen, Germany, in collaboration with the Deutsche Bunsen-Gesellschaft für Physikalische Chemie (DBG).
The DBG and the organizing committee of this year’s Bunsen-Tagung are pleased to showcase recent research either on the main topic of high-resolution structural methods in material and life sciences, or on general physical chemistry.
This themed collection is Guest Edited by Sarah Köster (Georg-August-University Göttingen), Melanie Schnell (Christian-Albrechts-Universität zu Kiel, Deutsches Elektronen-Synchrotron), Walter Richtering (RWTH Aachen University) and Dominik Wöll (RWTH Aachen University).
