The surface-specific nonlinear optical techniques are highly complementary to most conventional surface probes utilizing charged particles. Being purely optical, they can access interfacial systems that are otherwise difficult to probe. In this talk, I will talk about our recent in situ nonlinear optical studies on: 1) electrochemical reactions at the buried electrode/electrolyte interfaces; 2) the interaction between adsorbates and lattice on catalytic oxide surfaces. The unique in situ capability of the technique brings us new insight into these systems toward the mechanistic understanding of related surface phenomena.
