Chemical shifts in the Kα1,2 and Kβ1,3 X-ray emission spectra for halogen compounds of elements with atomic numbers ranging from 22 to 29 were measured using a wavelength-dispersive X-ray fluorescence spectrometer

This study aimed to investigate the chemical shifts and full widths at half maximum (FWHM) of the Kα 1,2 and Kβ 1 , 3 X-ray emission lines in selected halogen compounds of elements with atomic numbers ranging from 22 to 29. A Wavelength-Dispersive X-ray Fluorescence (WDXRF) spectrometer was employed for this analysis. The FWHM differences (ΔFWHM) of these emission lines were calculated by using the corresponding metallic element as a reference. The data revealed a clear pattern, showing larger chemical shifts for fluorine-containing compounds compared to chlorine-containing ones. In addition, the Kβ 1,3 lines generally show larger chemical shifts and wider full widths at half maximum (FWHM) compared to the Kα lines. The chemical shift also tends to increase as the number of coordinating ligand atoms rises. • The study focused on analyzing the chemical shifts and full widths at half maximum (FWHM) of Kα and Kβ 1 , 3 X-ray emission lines in halogen compounds of elements with atomic numbers between 22 and 29. • A Wavelength-Dispersive X-ray Fluorescence (WDXRF) spectrometer was used for precise measurements of the X-ray emission lines. • The study found that fluorine-containing compounds exhibited larger chemical shifts compared to chlorine-containing compounds. • The differences in full width at half maximum (ΔFWHM) of these emission lines were calculated using the corresponding metallic elements as references. • The Kβ1,3 lines generally showed larger chemical shifts and broader FWHM compared to the Kα lines. • A correlation was observed between the chemical shift and the number of coordinating ligand atoms, with shifts increasing as the number of ligands increased.
