X‐ray Absorption Spectroscopy is now one of the major tool for the study of the structure and of the electronic structure in material science as well as in atomic and molecular physics, in biology and chemistry. Beside an aspect of a routine experiment‐maybe the one where the turnover is the higher among the experimental stations of any synchrotron radiation facility ‐ new developments of the technique itself do appear continuously: improvements on the data colleciton as well as improvements of the interpretation of the results. This paper will then give some examples of such situation.
