the relatively short wavelengths of 0. 01Å to 100Å, with hard X-rays on one end and soft X-rays on the other. They are conventionally produced by either the conversion of the kinetic energy of charged particles into radiation or the excitation of atoms in a target upon which fast moving electrons im

The absorption, normally expressed in terms of absorption coefficient (.), can be determined from a measurement of the attenuation of X-rays upon their passage through a material. When the X-ray photon energy (.) is tuned to the binding energy of some core level of an atom in the ma

These variables or functions can then be determined from model compounds or from theoretical calculations. For some specialized applications or in some particular systems, however, this phenomenological theory is inadequate and .

Furthermore, the very same advantageous characteristics of EXAFS (short-range, single-scattering) are also its serious limitati

As a result of such measurements on a large number of compounds, the most commonly occurring stereochemistries for the various co-ordination numbers have been established. We shall deal with these in turn but first it will prove useful to consi
