Benchmarking Core-Level X-ray Absorption with MRSF-TDDFT, RASPT2, and Stochastic GAS Using the XABOOM Set

Rapid advances in X-ray free-electron laser facilities are producing X-ray absorption spectra (XAS) with unprecedented detail, creating a pressing need for theoretical methods that are both accurate and computationally efficient to interpret subtle spectral features. In this study, we benchmark two cost-effective ele...

Deciphering the internal conversion and triplet formation in thymine via time-resolved multi-center X-ray photoelectron spectroscopy

The photostability of DNA nucleobases relies on ultrafast nonradiative relaxation following ultraviolet excitation. In thymine, the competition between internal conversion (IC) and intersystem crossing (ISC) determines the balance between ultrafast energy dissipation and potentially long-lived photochemistry. However,...

Modular integration of MRSF-TDDFT, NAMD, and QM/MM for excited-state dynamics on the OpenQP platform.

A balanced and efficient description of excited states is essential for accurately capturing ultrafast relaxation processes. In this context, the recently developed mixed-reference spin-flip time-dependent density functional theory (MRSF-TDDFT) has demonstrated strong performance. However, its broader applicability to...

Nonadiabatic Dynamics of Uracil in Aqueous Solution from QM/MM in Periodic Boundary Conditions Combined with Mixed-Reference Spin-Flip TDDFT.

Understanding the excited-state dynamics of nucleobases in aqueous environments is essential for elucidating the mechanisms underlying DNA and RNA photostability. While puckered uracil structures have been theoretically predicted and observed in the gas phase following UV excitation, their behavior in solution remains...
