Reactions in Time and Space: Future Opportunities for Spectroscopy and Beyond - CHESS 2030 Workshop

Understanding chemical reactivity requires knowledge of every step of a reaction, including the structures of intermediate species, ideally under operando conditions.  The metastable nature of reaction intermediates necessitates time-resolved measurements, often on the order or seconds to milliseconds.  We plan an interdisciplinary workshop that will explore applications of time-resolved x-ray spectroscopy to in situ and operando catalytic systems.  Systems that will be explored include: 

Materials and Systems

• Biological and enzymatic catalysis at ambient temperatures and pressures using microfluidics
• Operando electrochemistry 
• Heterogeneous reactions at elevated temperature and pressure
• Pump-probe reactions

Experimental Tools:

• X-ray absorption spectroscopy (XAS) and EXAFS
• One- and two-color x-ray emission spectroscopy (XES)
• Scanning and dispersive measurements
• High energy resolution fluorescence detected XAS and resonant XES
• Simultaneous “on-line” sample characterization (e.g. optical spectroscopy) 
• Complementary quantum chemical computations

All times are Eastern Time.
