Reaction Dynamics at Solid Surfaces Studied by Time-Resolved SFG Spectroscopy: Structural Change of Adsorbates by Irradiation of Ps Laser Pulses

摘要

The irradiation of picosecond laser pulses causestemperature jump at the surface and the surface molecules arethermally exited to form the reaction intermediates. The directobservation of the surface by sum-frequency generationspectroscopy enables us to identify structure of intermediates.The successful application of this method, the study ofdecomposition of formate on NiO (111) surface, is discussed in this article.
