Recent Achievement and Perspectives in Synchrotron Radiation X-Ray Absorption Spectroscopy

2003

During the last 20 years, x-ray absorption spectroscopy (XAS) has found extensive application in the materials science [1, 2, 3]. solution chemistry [4], biology [5]. therapeutic chemistry [6] and geochemistry. However. it is relatively recently XAS methods have been utilized for measurements on archaeological materials [7,8].

XAFS study of gadolinium and samarium bisporphyrinate complexes.

2001

The comparative X-ray absorption spectroscopy study of gadolinium and samarium bisporphyrinate complexes represented by the formulas Gd(III)H(oep)(tpp), Gd(III)(oep)(2), Gd(III)H(tpp)(2) and Sm(III)H(oep)(tpp), Sm(III)(oep)(2), Sm(III)H(tpp)(2) is reported. The XAFS spectra are recorded on the LURE-DCI storage ring (Orsay, France) in transmission mode on the microcrystalline samples at the Gd and Sm L(3) edges. The local environment for Ln(3+) ions has been reconstructed applying one-shell and two-shell XAFS analysis procedures. The protonated and nonprotonated bisporphyrinate complexes present different XAFS features. After our analysis on the title derivatives, the gadolinium ion (at 80 K…
