Chemical shift and full widths at half maximum (FWHM) intensity of chromium Kα and Kβ 1, 3 lines were examined for 12 kinds of materials containing chromium (CH 3 CO 2 ) 7 Cr 3 (OH) 2 , CrK(SO 4 ) 2 .12H 2 O, Cr(NO3) 3 .9H 2 O, Cr 2 O 3 , CrF 2 , CrF 3 .4H 2 O, CrCl 2 , CrCl 3 , CrCl 3 .6H 2 O, [CrCl 2 (H 2 O) 4 ]Cl.2H 2 O, Cr 2 (SO 4 ) 3 .15H 2 O, CrO and Cr metal by wavelength‐dispersive X‐ray fluorescence (WDXRF) spectrometry. The chemical shifts, asymmetry index and the half‐widths of both the X‐ray emission lines show interesting trends with the oxidation state of chromium. It was observed that the chemical shifts for F compounds are higher than Cl compounds. It was also found larger chemical shifts and FWHM for Kβ 1, 3 lines than Kα ones. It should be noted that the magnitude of chemical shifts increases with increase in the number of ligand atoms. Copyright © 2009 John Wiley & Sons, Ltd.
