Abstract

Dips appearing in the L-edge total fluorescence yield (TFY) spectra of transition-metal ions in aqueous solutions have been recently attributed to, orbital mixing of the solute with the solvent orbitals. Here we compare the L-edge TFY, Oxygen K α and Co 2+ L l(3s → 2p 3/2), L η(3s → 2p 1/2), L α(3d → 2p 3/2) and L β(3d → 2p 1/2) -edge partial fluorescence yield with the transmission spectrum. We thereby confirm that these mixed orbitals lead to electron delocalization between the valence d-orbitals of the transition metal and the valence bands of the solvent molecules, quenching their X-ray fluorescence.
