Abstract
New interface‐selective second‐ (χ^(2)^) and fourth‐order (χ^(4)^) nonlinear spectroscopic techniques have been developed. χ^(2)^ electronic sum frequency generation (ESFG) spectroscopy enables us to obtain interfacial electronic spectra with an unprecedented high signal‐to‐noise ratio and dense wavelength data points. Frequency‐domain χ^(4)^ Raman spectroscopy provides vibrational spectra of interfaces for a very wide wavenumber range covering the whole fingerprint region. Because these new even‐order electronic and vibrational nonlinear spectroscopies utilize only visible and/or near‐infrared laser pulses, they are applicable to a variety of “buried” interfaces that are not readily accessed by the other existing methods.
