Hydrogenation of Uracil in Solid Para -Hydrogen: Infrared Spectra of Monohydrogenated Radicals (5 H -C4H5N2O2, 6 H -C4H5N2O2, and 4 OH -C4H5N2O2) and Their Implications for RNA-Related Chemistry in the Interstellar Medium
Uracil (C4H4N2O2), an essential RNA nucleobase central to the RNA World hypothesis and the prebiotic emergence of life, has been detected in pristine asteroid samples, yet its survival mechanism in nonenergetic interstellar environments ...

Morphological Effects on the Heterogeneous Freezing of Droplets Containing Different Ice Nucleating Particles
Atmospheric aerosol particles can act as ice nucleating particles (INPs) and influence cloud formation, precipitation, and radiative forcing. However, ice nucleation remains poorly understood because atmospheric aerosols exhibit complex ...

Vibrational-Gated Intersystem Crossing in Phenolphthalein Dianion: A TDDFT Insight into the Fluorescence Quenching Mechanism
The structural rigidity of molecular frameworks plays a pivotal role in modulating intersystem crossings (ISCs). Here, we systematically investigate the distinct fluorescence behaviors of the phenolphthalein dianion (PHP2–) and the fluor...

Machine-Learning-Assisted Tuning of Exchange–Correlation Functional Parameters for the eXact-Integral Simplified Tamm-Dancoff Approximation Method
Here, we improve the accuracy of eXact-integral simplified Tamm–Dancoff approximation (XsTDA) excitation energies through reference-guided and machine-learning-assisted molecule-specific tuning of exchange–correlation functional paramete...

E → Z Isomerization Catalyzed by Organic Photosensitizers Explored by Nonorthogonal Multireference Wave Function Methods
Triplet–triplet energy transfer (TEnT) processes, where energy is transferred from the triplet state of a donor (or photosensitizer, PS) to the singlet ground state of an acceptor (substrate), were applied to investigate E → Z photocatal...

Active Thermochemical Tables: A Revision of the Enthalpy of Formation of Gas-Phase Sulfur Atom and a Refinement of the Thermochemistry of Several Other Key Sulfur Species
Using the Active Thermochemical Tables (ATcT) approach, the 298.15 K standard enthalpy of formation of sulfur atom has been revised to 279.10 ± 0.12 kJ mol–1 (276.85 ± 0.12 kJ mol–1 at 0 K). The new ATcT value is nearly 2 kJ mol–1 higher...

A Theoretical Kinetic Study of the Reaction between CH3OȮ and ṄH2
In NH3/CH4 combustion, the oxidation product CH3OȮ derived from ĊH3 radicals can react with abundant ṄH2 radicals, and the CH3OȮ + ṄH2 ↔ CH3Ȯ + H2NȮ reaction can significantly increase reactivity and influence the model-predicted ...

Theoretical Study on Vibronically Resolved Spectra of Six Heteroatom-Doped Benzannulated [4]Helicenes: Vibrational Mode Assignments and Substituent Effects
Helicene derivatives have potential as chiral luminescent materials. However, the effect of substituents on the vibrational structures of their spectra is not yet clear. In this work, we used time-dependent (TD) and time-independent (TI)...

Electron-Number Response of QTAIM Delocalization Indices: A Differential Decomposition into Population and Orbital-Relaxation Contributions
This work establishes a differential framework for analyzing the electron-number response of QTAIM delocalization indices within the piecewise-linear ensemble formalism of conceptual density functional theory (C-DFT). The resulting first...

The Photocycloaddition Reaction and Excited-State Dynamics of Benzo[ g ]quinoxaline Derivatives Featuring X-Aggregated Dimers
Reversible photocycloaddition reactions of anthracene-based compounds have attracted considerable attention. However, the solid-state cycloaddition mechanism is unclear, and the cycloaddition behavior of X-aggregated anthracene dimers re...
