摘要: The electronic structure of a Ti3+ aqueous solution is studied by liquid-jet soft X-ray photoelectron (PE) spectroscopy. Measured valence and Ti 2p core-level binding energies, together with the resonant (RPE) spectra derived partial electron-yield L-edge absorption (PEY-XA) spectra, reveal mixing between metal 3d water orbitals. Specifically, ligand states character are identified through enhancement signal intensities in RPE spectra. An observed satellite peak assigned to several different metal–ligand states. Experimental energies delocalized nature respective orbitals supported ground-state calculations. We also show that choice detected Auger-electron-decay channel, from which PEY-XA obtained, experimental sensitivity interactions electrons solvent can be varied. effect such state-dependent relaxa...
