Dynamic enhanced vibrational spectroscopy in the near field such as surface-enhanced Raman scattering (SERS) and surface-enhanced infrared absorption (SEIRA) has recently received keen interest because it shows extremely high sensitivity in the observation of vibrational spectra of molecules. Studies of dynamic enhanced vibrational spectroscopy are of particular importance from the points of applications as well as basic science. A few groups succeeded in the single molecule detection by SERS, stimulating further possibilities of the applications of dynamic enhanced vibrational spectroscopy. The purpose of this review is to provide brief description of dynamic enhanced vibrational spectroscopy in the near field and to introduce our recent studies which aim at the elucidation of the mechanism of the surface enhancement.
