Surface nonlinear optics can be used for study of interfaces. It is found that nonlinear optical effects can be greatly enhanced on a rough noble metal surface because of the large local-field enhancement due to local plasmon resonances and the lightning rod effect. Second harmonic generation is sensitive enough to detect adsorbed molecular monolayers on surfaces, and can be used to study the molecular adsorption and desorption process at a solid-liquid interface. Monolayer spectroscopy by nonlinear optical techniques is also possible. The polarization dependence of the nonlinear output can yield valuable information about the molecular orientation on a surface.
