چکیده انگلیسی
The chemical shift in Kα and Kβ1,3 X-ray emission lines of 47Ag, 48Cd and 50Sn compounds have been studied by using highly equipped advanced S8 TIGER WDXRF spectrometer. From the results, it is found that halogen compounds are more sensitive for chemical shifts than other compounds. With change of transition probabilities and outermost shell energy levels, chemical shift measured in Kβ1,3 X-ray emission lines are observed more than that of Kα emission lines. It is also found that chemical shift (ΔE) and effective charge (q) are increased with increasing number of ligands attached to the central metal atom. To show the dependency behaviour of chemical shift and effective charge with each other, we establish a linear relation between them in different 48Cd and 50Sn compounds.
