Abstract | This talk gives an introduction to sum-frequency spectroscopy that we have developed over the years.It is a nonlinear optical technique that can provide more (sometimes unique) information about materials than linear optical techniques. In particular, its applications to surfaces and interfaces have greatly expanded the scope of surface science research.A number of relevant examples in different fields will be described to illustrate the power and uniqueness of the technique.Recent progress will be discussed. |
