摘要：

Energy dispersive EXAFS (EDE) data have been analyzed for the hydrogenation of styrene by the rhodium zwitterionic Rh(l) complexes, Rh(sulphos)(cod) and hydroformylation of I-hexene by the Rh(sulphos)(CO)(2) using curved wave theory with ab initio phase-shifts. The derived parameters for metal compounds were in good agreement within experimental error of 0.02-0.05 Angstrom for the bond distances. The bond lengths in the rhodium complexes were refined at average distances of Rh-C 1.90 Angstrom, Rh-P 2.31 Angstrom and Rh-O 2.90 Angstrom consistently. This is a good start for the quantitative analysis of the dispersive EXAFS techniques at variable temperatures and high pressures.
