✦ Synopsis

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.
