Nickel K–L (Kα) x‐ray fluorescence spectra of 32 kinds of materials containing nickel [NiF 2 , NiSO 4 , Ni(CO 3 ) 2 , Ni(OH) 2 , Ni 2 O 3 , NiTiO 3 , NiO, NiFe 2 O 4 , NiCl 2 , NiBr 2 , NiI 2 , LiNiO 2 , NiS, NiTe, Ni 3 P, metal, LaNi 5 , Ni 2 P, NiCr, Ni 2 Si, NiB, NiSi 2 , acetylacetonate, K 2 Ni(CN) 4 , and some nickel complexes] were measured using a double‐crystal x‐ray fluorescence spectrometer. The shift, asymmetry and spin–orbit splitting energy were extracted from the measured spectra. The asymmetric Kα lineshape was deconvoluted by Lorentzian functions. It is demonstrated that the chemical state of nickel in an unknown material can be analyzed by the use of these parameters. Copyright © 1999 John Wiley & Sons, Ltd.
