X-ray absorption spectroscopy (XAS) has been revealed to be a potential tool for determining the electronic and geometrical structure of transition metal compounds. The position and shape of X-ray absorption discontinuities have been used to deduce structural and chemical bonding information on the compounds. This book, therefore, provides X-ray K absorption spectroscopic study which is a very strong informative experimental approach to study the coordination geometry and bonding relation in metal compounds. The X-ray absorption measurements were performed at the BL-8 DEXAFS beamline at...
