Correlation between X-ray chemical shift and partial charge in Tc(IV) complexes: Determination of Tc partial charge in $Tc_nO_y^{(4n-2y)+}$

Abstract : The chemical shift of the X-ray absorption K-edge of Tc(IV) complexes determined by X-ray Absorption Spectroscopy (XAS) measurement was studied. A correlation between edge position (ΔE) and partial charge on Tc atoms (δTc) was determined. This correlation was used to determinate δTc in TcnOy(4n-2y)+. Furthermore, a theoretical relation between δTc and the charge of TcnOy(4n-2y)+, was also established and the overall charge of this complex was estimated.
