✦ Synopsis

In this work our previous study about chemical effects in the Ka spectra of S compounds employing high-resolution X-ray spectroscopy has been extended to the Kb emission spectra. The measurements were performed with a wavelength dispersive single crystal spectrometer operated in the von Hamos geometry having an energy resolution comparable to the natural linewidth of the measured Kb X-ray lines. The target fluorescence was produced by irradiating the samples with the bremsstrahlung from an X-ray tube. The energies and widths of the main components in the Kb emission spectrum are given for different sulfur compounds (sulfide, sulfite, sulfate). The measured energy shifts between the Kb lines of the compounds and elemental sulfur are presented as a function of the sulfur oxidation state and compared with the results obtained from the former Ka measurements.

The KB emission spectra of chromium in oxidic compounds were investigated by means of the fluorescent method. The origin of the main KB lines is discussed using MO theory and the dependence of the energy positions on the chemical bond is reported. The compounds studied include the oxides Cr,09 Cr02

Sulfur Ka,., X-ray transitions are calculated for a series of systems using the equivalent-cores approximation in which sulfur with a core hole is replaced by a Cl+ ion. Charge densities on such chlorine atoms are evaluated using the INDO method and correlated with experimental transition energies.
