48_47b/2009Inside Cover: Label-Free Chemical Imaging of Catalytic Solids by Coherent Anti-Stokes Raman Scattering and Synchrotron-Based Infrared Microscopy (Angew. Chem. Int. Ed. 47/2009)

The catalytic conversion of thiophene derivatives on individual zeolite ZSM-5 crystals was studied by using a combination of multiplex coherent anti-Stokes Raman scattering (CARS) and synchrotron-based IR microscopy. In their Communication on page 8990 ff., B. M. Weckhuysen et al. show how label-free chemical imaging of reactant/reaction products can be achieved with high spatial resolution. Vibrational bands in the CARS and IR spectra evidenced interaction of thiophenes with the zeolite framework, followed by ring opening.
