Abstract
Unstable intermediates are indispensable ingredients of chemical react ions, but their identification at solid surfaces has been hampered by the lack of techniques to detect short-lived and fractionally generate d species. We succeeded in identifying the intermediate in a thermal d ecomposition reaction by utilizing the picosecond temperature jump ind uced by the irradiation of laser pulses and the observation by sum-fre quency generation spectroscopy. We verified that the decomposition of formate on the NiO(lll) surface is preceded by the transformation of s table bidentate formate to unstable monodentate formate, which is the reactive intermediate, and two species are found to be in equilibrium before decomposition.
