Chemical dependence of interatomic X-ray transition energies and intensities -: a study of Mn Kβ" and Kβ2,5 spectra

A study of ligand (N, O, F) 2s to metal (Mn) 1s 'interatomic' or 'crossover' X-ray transitions is reported. We show that the energy of the K beta " feature is related to the ligand 2s binding energy and can be used to identify the type of ligand. For oxygen-ligated Mn compounds, the strength of the K beta " transition decreases exponentially with increasing Mn-O distance. This can be used to predict distances to similar to 0.1 Angstrom. The K beta(2,5) energy shows shifts of similar to 1 eV per unit oxidation state. K beta " and K beta(2,5) transitions are a promising tool for structural characterization of transition-metal complexes. (C) 1999 Elsevier Science B.V. All rights reserved.
