Chemical effects on the K-beta/K-alpha X-ray intensity ratios for some Mn, Ni, and Cu complexes of a new schiff-base with salen N2H2 type were investigated. The samples were excited by 59.543 keV gamma-rays from a Am-241 annular radioactive source. K X-rays emitted by samples were counted by a Si(Li) detector with resolution 157 eV at 5.9 keV. We observed the chemical effect on the K-beta/K-alpha X-ray intensity ratios for Mn, Ni and Cu complexes. The experimental results showed that the K-beta/K-alpha X-ray intensity ratios for compounds with complexes are generally larger than those with salt form. The experimental values have been compared with the other experimental and the theoretically calculated values of pure elements. The results are in very good agreement with the others.
