Session Abstract

Data analysis of both XAFS spectra and crystallographic data is the bottleneck to retrieving the relevant structural information of the molecular system under investigation. This fact has become more critical recently since the rapidly growing number of in situ or operando data acquisition to monitoring dynamic chemical systems and chemical reactions, such as batteries or in catalysis. The considerable amount of data usually produced is calling for a suitable strategy for their treatment in a reliable way and within reasonable time frame. This MS focuses on advanced and efficient methods to extract as much information as possible in XAFS and crystallographic data. Not only chemometric tools will be emphasized but also application in molecular systems of spectroscopic and scattering techniques to disclose reaction mechanism.
