Principles of Surface-Enhanced Raman Spectroscopy ...

Publisher Summary. This chapter discusses the fundamentals of the surface-enhanced Raman scattering (SERS) effect. SERS consists in using the large local field enhancements that can exist at metallic surfaces (under the right conditions, typically by profiting from localized surface plasmon resonances) to boost the Raman scattering signal of molecules at (or close to) the surface.
