Valence Threshold Photoionization Spectra of C5$_5$H and C5$_5$H2$_2$ Isomers

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
Mass‐selected threshold photoelectron spectra (TPES) of l‐C5H, HC5H, and c–C3H‐CCH were recorded using double‐imaging photoelectron‐photoion coincidence spectroscopy. These transient species were generated in situ by hydrogen abstraction from cyclopropylacetylene and 1,3‐pentadiyne.

Spectroscopic Investigation of Thioacrolein by Variational and Perturbational Approaches

Journal of Computational Chemistry, Volume 47, Issue 10, 15 April 2026.
The vibrational and rotational spectra of trans and cis‐thioacrolein were studied by high levels of electronic and vibrational structure theory. Comparisons with experimental results are provided for several molecular quantities. ABSTRACT The vibrational spectra of trans and cis‐thioacrolein have been studied by 2nd order vibrational perturbation ...

Prebiotic Organic Chemistry of Diketopiperazines

Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.
Diketopiperazines (DKPs) are considered essential in many life forms, but their prebiotic importance has not been fully understood. This review aims to discuss prebiotic organic chemistry for experimentally and computationally simulated reactions involving DKPs. ABSTRACT Even though the significance of amino acids and polypeptides is well recognized in

15 yr of Interstellar Neutral Hydrogen Observed with the Interstellar Boundary Explorer

The Astrophysical Journal Supplement Series
The interactions of our heliosphere with the surrounding local interstellar medium (LISM) lead to a range of observable phenomena such as energetic neutral atoms (ENAs) from the boundary regions of the heliosphere and the influx of interstellar neutrals (

C. F. v. Weizsächer on Quasistationary Isotropic Turbulence Compared With Onsager's Statistical Hydrodynamics

Natural Sciences, Volume 6, Issue 2, April 2026.
v. Weizsäcker and Heisenberg began their turbulence collaboration in 1945 while still quarantined at Farm Hall. Their papers were submitted separately in 1946 from Göttingen. v. Weizsäcker had derived the 5/3 law for dissipation while using dimensional analysis in real space.

Observed Timescales of Stellar Feedback in Star-forming, Low-mass Galaxies

The Astronomical Journal
Understanding the timescales of atomic gas turbulence is crucial to understanding the interplay between star formation and the interstellar medium (ISM). To investigate the timescales of turbulence low-mass galaxies (10 ^6.8

Composite Single‐Reference and Explicitly Correlated Multireference Calculations on the Mechanism of Pyrrole Pyrolysis

Journal of Physical Organic Chemistry, Volume 39, Issue 4, April 2026.
New calculations have been applied to the pyrolysis of pyrrole under shock‐tube conditions and to the radical‐radical reaction between allyl and •CN at low temperature and pressure, using the same mechanistic scheme for both. ABSTRACT The pyrolysis of pyrrole has previously been studied in shock‐tube experiments and in jet‐stirred reactors. The results
