Article Abstract

We report a theoretical and experimental study of the high resolution resonant K(α) X-ray emission lines around the chlorine K-edge in gas phase 1,1-dichloroethylene. With the help of ab initio electronic structure calculations and cross section evaluation, we interpret the lowest lying peak in the X-ray absorption and emission spectra. The behavior of the K(α) emission lines with respect to frequency detuning highlights the existence of femtosecond nuclear dynamics on the dissociative Potential Energy Surface of the first K-shell core-excited state.

Halogenation of organic molecules causes chemical shifts of C1s core-level binding energies that are commonly used as fingerprints to identify chemical species. Here, we use synchrotron-based X-ray photoelectron spectroscopy and density functional theory calculations to unravel such chemical shifts by examining different partially fluorinated pentacene derivatives. Core-level shifts occur even for carbon atoms distant from the fluorination positions, yielding a continuous shift of about 1.

Article Synopsis
  • - The study showcases a method called mixed-reference spin-flip time-dependent density functional theory (MRSF-TDDFT) that effectively handles core-hole particle (CHP) orbital relaxation in core electron spectra.
  • - With the inclusion of scalar relativistic effects, the method demonstrated high accuracy in predicting K-edge excitation energies for various molecules, achieving a root mean square error (RMSE) of around 0.5 eV, especially notable for sulfur and chlorine.
  • - Overall, MRSF-TDDFT not only accurately describes core electron spectra for molecules like thymine but also enhances our understanding of electronic transitions and energy levels in both ground and excited states.

X-ray Transient Absorption Spectroscopy (XTAS) and theoretical calculations are used to study CCl prepared by 800 nm strong-field ionization. XTAS simultaneously probes atoms at the carbon K-edge (280-300 eV) and chlorine L-edge (195-220 eV). Comparison of experiment to X-ray spectra computed by orbital-optimized density functional theory (OO-DFT) indicates that after ionization, CCl undergoes symmetry breaking driven by Jahn-Teller distortion away from the initial tetrahedral structure (T) in 6 ± 2 fs.

Chlorine covalently bonded to an open shell metal is present in many materials with desirable or intriguing physical properties. Materials include highly luminescent nontoxic alternatives to lead halide perovskites for optoelectronic applications KCuCland RbCuCl, enantiomorphic CsCuClthat presents magneto-chiral dichroism at a low temperature, and cubic KRuClthat possesses a singlet ground state generated by antiparallel spin and orbital angular momenta. Structural chirality of CsCuClhas been confirmed by resonant x-ray Bragg diffraction.
