In this chapter we provide an overview on how the potentialities of EXAFS can be expanded by the proper use of the so called “related techniques”. We stress the relevance of combining information at long, medium and local range in order to have a complete structural view of the investigated materials. We show how it is possible to obtain EXAFS-like information from low Z elements, how local-range contributions coming from amorphous and crystalline phases can be disentangled, how EXAFS-like contribution coming from the same element hosted in different crystallographic sites can be separated. Finally, we discuss the relevance, the advantages and the criticalities of the simultaneous data collection with different techniques.

Abstract

In this chapter we provide an overview on how the potentialities of EXAFS can be expanded by the proper use of the so called “related techniques”. We stress the relevance of combining information at long, medium and local range in order to have a complete structural view of the investigated materials. We show how it is possible to obtain EXAFS-like information from low Z elements, how local-range contributions coming from amorphous and crystalline phases can be disentangled, how EXAFS-like contribution coming from the same element hosted in different crystallographic sites can be separated. Finally, we discuss the relevance, the advantages and the criticalities of the simultaneous data collection with different techniques.
