Basics of Surface-Enhanced Raman Scattering SERS

A new spectroscopic method that appears to be promising for answering some basic questions regarding surfactant adsorption, coadsorption, and displacement reactions on charged model surfaces is Surface-Enhanced Raman Scattering (SERS) spectroscopy [1—6]. This enables researchers to characterize in situ the chemical identity, structure, orientation, and chemical reaction of species adsorbed at surfaces. [Pg.152]

It is not in the scope of the present chapter to review all possible experimental setups for the various types of Raman scattering classical, microprobe, Fourier transform (FT), coherent anti-Stokes (CARS), surface enhanced (SERS), hyper (HRS), photo-acoustic (PARS), and so forth (see, e.g.. Refs. 29-31). A basic Raman-scattering instrument requires a laser-light source, an appropriate sample holder, a sample illumination optical unit, a scattered-light collection optical unit (these two may be combined in one system), a disperser (spectrometer) or an interferometer, a light detection unit, a recorder, and an appropriate microcomputer able to drive, control, and record all of the experimental parameters as well as the results and their processing.
