Measurement and modelling of the electron energy loss near-edge structure associated with a particular core-loss edge allows, in favourable cases, the identification of a gross structure reflecting the nearest neighbour environment of the atom undergoing excitation. We present a methodology for the investigation and cataloguing of such co-ordination fingerprints and indicate relevant applications of the technique in both a qualitative and semi-quantitative manner.
