  • Stepwise deuteration of protonated methane CH5+ — a fluxional structure that undergoes ‘hydrogen scrambling’ — leads to dramatic changes in the infrared spectra of the isotopologues. The spectra can be assigned using ab initio quantum simulations that account for the non-classical occupation — by H and D atoms — of topologically different sites within the molecule.

  • Sulfur allotropes are proposed to be an important sulfur reservoir in molecular clouds, but spectroscopic data to test this hypothesis are limited. Here the authors measure laboratory far-infrared spectra of cold isolated S8 molecules, which show a near-perfect match with calculations, and examine their fragmentation pathways.

  • Recent detections of nitrogen-bearing polycyclic aromatic hydrocarbons (N-PAHs) in the interstellar medium prompt questions about how these molecules form at low temperatures. Here a combination of kinetic studies and spectroscopy reveals an efficient formation route from monocyclic aromatic hydrocarbons to N-PAHs.

  • It is essential to understand the effect of molecular vibration on charge transport for better design of molecular electronics. Here, the authors test two benchmark aromatic motifs and show how the coupling between π electrons and molecular vibration is affected by molecular edge topology.
