IR spectroscopy can provide a variety of information, including:
Identification of Functional Groups: Different functional groups absorb IR radiation at specific frequencies, allowing for their identification. Monitoring Reaction Progress: By observing changes in the IR spectrum over time, one can monitor the progress of a catalytic reaction and identify intermediate species. Surface Species: IR spectroscopy can detect species adsorbed on the surface of a catalyst, providing insights into the nature of active sites and reaction intermediates. Quantitative Analysis: The intensity of absorption bands can be used to quantify the concentration of different species.
