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 ...
Resonance Raman can enhance the Raman scattering intensity by a factor of 102-106 and improves signal-to-noise. ...
The wavelength chosen will impact Raman intensity, spatial resolution, background fluorescence, acquisition time, and the potential cost of a Raman system. ...
The longer the spectrometer focal length the better the spectral resolution. Typical benchtop Raman systems use a 200 – 250 mm focal length which provides standard resolution whilst keeping the instrument compact. ...
Introduction Surfaced enhanced Raman spectroscopy, (SERS), is an enhancement technique used to overcome the challenges seen with weak Raman scattering. ...
