In catalysis, IR spectroscopy is invaluable for several reasons:
1. Identification of Active Sites: By examining the vibrational frequencies of adsorbed species, IR spectroscopy can help identify the active sites on a catalyst. 2. Monitoring Reaction Intermediates: IR spectroscopy can detect transient intermediates formed during catalytic reactions, providing insights into reaction mechanisms. 3. Surface Interactions: It helps elucidate the interaction between reactants and the catalyst surface, which is crucial for understanding catalytic activity and selectivity.
