In the work X-ray K edges of chromium dichalcogenides CuCr1-xMx′S2 (M = V, Fe; x = 0-0.40) and MCrX2 (M = Cu, Ag, Na; X = O, S, Se) were studied experimentally and theoretically. Comparison of fine structures of experimental XANES spectra obtained using a synchrotron radiation source and theoretical absorption spectra modelled using FDMNES software package allows one to study the influence of types of intercalate M, chalcogene X and also the effect of the cation substitution of chromium atoms by vanadium and iron on XANES structure of K edges in CuCr1-xMx′S2 and MCrX2.
