Asymmetry indices, chemical shifts and full widths at half maximum intensity (FWHM) of the chromium Kα 1 and Kα 2 x‐ray emission lines were studied in chromium metal, some of its divalent, trivalent, tetravalent and hexavalent compounds, and minerals, catalysts and glassy materials by an x‐ray fluorescence excitation method. The asymmetry indices were found to depend on the number of unpaired 3d electrons. The chemical shifts, spin—orbit splittings, asymmetry indices and the half‐widths of both the X‐ray emission lines show interesting trends with the oxidation state of chromium.
