    Time-Resolved X-Ray Spectroscopy from the Atomic Orbital Ground State Up by Daniel Jost, Eder G. Lomeli, Ta Tang, Joshua J. Kas, John J. Rehr, Wei-Sheng Lee, Hong-Chen Jiang, Brian Moritz, Thomas P. Devereaux

    Published 2025-01-01
    “…In this paper, we will present simulations of each of these spectroscopies using a time-domain full atomic multiplet, charge-transfer Hamiltonian adapted to study the properties of a generalized cluster model including a central transition-metal ion caged by ligand atoms in a planar geometry. The numerically evaluated trXAS and trRIXS cross sections for representative electron configurations 3d^{9} and 3d^{8} demonstrate the insights that can be obtained from charge-transfer pumping and how this nonequilibrium process affects ground- and excited-state properties. …”

    Light-Induced Tyrosine Radical Formation from Ruthenium-Tyrosine Complex Anchored to SnO2 Semiconductor by Raed Ghanem

    Published 2008-01-01
    “…A ruthenium(II)-tris(bipyridyl) complex covalently linked to an L-tyrosine ethyl ester through an amide bond was anchored to the surface of nanocrystalline SnO2 via four carboxylic acid groups linked to the bpy ligands. The apparent association constant for the association between ruthenium(II)-tris(bipyridyl) complex and SnO2 is 3.2×106M−1 and a degree of association up to 99% was determined. 450 nm excitation of the complex promotes an electron to a metal-to-ligand charge transfer (MLCT) excited state, from which the electron is injected into SnO2. …”
