One of the most interesting spectroelectrochemical techniques combines the fields of electrochemistry and Raman spectroscopy. Although the Raman effect was theoretically predicted by Smekal in 1923 [1] as well as by Kramers and Heisenberg in 1925 [2], the first physical evidence was found in 1928 by the Indian scientist Chandrasekhara Venkata Raman [3] and almost simultaneously by Soviet ...
Raman spectroscopy is a non-destructive analytical technique based on the inelastic scattering of photons related to the different vibrational modes of molecules. This discovery by C. V. Raman in 1928 resulted in a simple yet effective method to determine the structure of simple molecules that continues to grow in popularity among the scientific community. As the spectrometer’s laser ...

Colloidal nanoparticles of gold and silver were used in Surface–Enhanced Raman Scattering (SERS) analysis of melamine and 4–aminobiphenyl. ...
The prepared gold network has shown a high activity to work as surface enhanced Raman scattering substrate. In view of its process simplicity, this template–free direct method can be further studied for large–scale fabrications of other low density metals and alloys with meso– and macroporous open framework structures.Keywords: ...
A new double-hole structure was presented to enable significantly enhanced local fields in the nano-holes, which has applications in non-linear optics and spectroscopy. Theory and experiments are presented for this double-hole structure, showing enhanced second-harmonic generation. We have used nano-hole arrays in surface plasmon resonance ...
