Brief Description of the SERS Effect

When organic molecules are close to (within a few A) or adsorbed on rough surfaces of certain metals, such as silver, copper, or gold, a very large enhancement of their Raman spectra (by a factor of ca. 106-108) may be observed. 

The main features of the SER(R)S effect can thus be summarized as follows
