Spectroscopic characterization is an essential aspect in heterogeneous catalysis research. When performed under reaction conditions, it provides a �sneak peek� of working catalysts including their many bulk and surface transformations and adsorbed species. These events on the catalyst surface provide valuable insights into the active sites and reaction elementary steps, information essential for the rational development of micro- and macrokinetic models of target reactions. In this talk, we will present an overview of current in situ spectroscopic techniques for the study of heterogeneous catalyzed reactions. In particular, we will focus on the evolution of transient spectroscopic techniques for the detection of surface reaction intermediates through examples from Oyama's group and others, including ozone decomposition, methanol and acetone oxidation, propylene epoxidation, and pyridine hydrodenitrogenation. Additionally, we will also highlight some recent and prospective advances in this area.
