This study aimed to investigate the chemical shifts and full widths at half maximum (FWHM) of the Kα1,2 and Kβ1,3 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 Kβ1,3 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.
