L-ABSORPTION SPECTRA OF DY COMPLEXES

The rare earth elements, compounds and complexes have evoked a great d eal of interest because of their peculiar structure, properties and in dustrial and biochemical importance. In the present paper, we present the analysis of various XANES features of the L-absorption edges of Dy complexes with ligands of biological importance (viz. acetylacetone ( acac), ethylacetoacetate (eaa), triphenyl phosphine oxide thiocyanate (tppo)(NCS), dipyridyl nitrate (dipy)(NO3), triphenyl phosphine oxide nitrate (tppo)(NO3), etc.) Such a study is helpful in understanding th e behaviour of the Dy(III) ion and its biological applications.
