Energy Dispersive EXAFS (EDE) data has been analysed for the nickel (3-diketonate catalysts, Ni(dpm)2, using curved wave theory with ab initio phaseshifts. The derived parameters for nickel intermediate compounds were in good agreement, within experimental error of 0.02-0.05 A for the bond distances. A stopped flow system was used for in situ time-resolved EDE studies on the nickel systems at room temperature. The growth of a pre-edge feature and change at the top of the edge can be clearly seen to show the reaction reached completion in less than 6 s indicates averaged distances of 3 Ni-O/C 2.00 A.
