Photoinduced enhancement of chemical shift sensitivity to local vibrations
Ana MartÃnez Gutiérrez, Oliver Alexander, Pablo Estévez Alonso +26
The advent of novel free-electron laser sources enabling time-resolved x-ray photoelectron spectroscopy (tr-XPS) provides a unique opportunity to monitor local chemical environment…

Unraveling real-time chemical shifts in the ultrafast regime
Daniel E. Rivas, Lorenzo Paoloni, Rebecca Boll +21
Traditional x-ray photoelectron spectroscopy (XPS) relies upon a direct mapping between the photoelectron binding energies and the local chemical environment, which is well-charact…

Core-hole Coherent Spectroscopy in Molecules
Emilio RodrÃguez-Cuenca, Antonio Picón, Solène Oberli +2
We study the ultrafast dynamics initiated by a coherent superposition of core-excited states of nitrous oxide molecule. Using high-level \textit{ab-initio} methods, we show that th…
