Abstract Selected examples in V K-edge X-ray Absorption Near Edge Structure (XANES) analysis of a series of vanadium complexes containing imido ligands (possessing metal-nitiogen double bond) in toluene solution have been introduced, and their pre-edge and the edge were affected by then structures and nature of ligands. Selected results m exploring the oxidation states of the active species in ethylene dimerization/polymerization using homogeneous vanadium catalysts [consisting of (imido)vanadium(V) complexes and Al cocatalysts] by X-ray absorption spectroscopy (XAS) analyses have been introduced. It has been demonstrated that the method should provide more clear information concerning the active species in situ, especially by combination with the other methods (NMR and ESR spectra, X-ray ciystallographic analysis, and leaction chemistry), and should he powerful tool for study of catalysis mechanism as well as for the structural analysis in solution.
