Chemical shifts in the X-ray L.BETA.2,15 and L.GAMMA.1 emission lines of tin and antimony.

Abstract

The spectral changes in the Lα2, Lα1, Lβ1, Lβ4, Lβ3, Lβ2, 15, and Lγ1 lines were measured for various compounds of tin and antimony using a two-crystal X-ray spectrometer. The chemical shift was observed in the Lβ2, 15 and Lγ1 lines depending on different oxidation states of tin and antimony. The shifts of both lines were almost comparable to each other for every compound tested. The compounds in lower oxidation states of Sn(II) and Sb(III) exhibited the positive shifts in Lβ2, 15 and Lγ1 lines relative to the respective lines from their metallic state, while those with the higher oxidation states of Sn(IV) and Sb(V) had the negative shifts of these lines. This fact suggests that oxidation state of tin and antimony can be readily distinguished by the measurements of their Lβ2, 15 and Lγ1 shifts. The chemical shifts in other L lines of both elements did not exceed the experimental error of about ±0.02 eV.
