Sensitive and isomer-specific analytical tools detect elusive intermediates and reveal reaction mechanisms. Photoelectron photoion coincidence spectroscopy, introduced in 1966, now serves as a reaction microscope, identifies intermediates, and delineates gaseous and surface-confined processes in heterogeneous catalysis.
