Resonance Raman spectroscopy
Videos
Resonance Raman spectroscopy is a variant of Raman spectroscopy in which the incident photon energy is close in energy to an electronic transition of a compound or material under examination. This sim
Energy level diagram showing relationship between Rayleigh, Raman, and resonance Raman scattering and fluorescence.
Surface-enhanced Raman spectroscopy or surface-enhanced Raman scattering is a surface-sensitive technique that enhances Raman scattering by molecules adsorbed on rough metal surfaces or by nanostructu

…light. It is especially useful for molecules that are both polar and polarizable. Surface-enhanced resonance Raman spectroscopy: A hybrid of RRS and surface-enhanced Raman scattering. The sample is applied to conducting nanoparticles and a laser matching the surface plasmon resonance of the nanoparticles is used as source. If the…
Raman spectrum of liquid 2-mercaptoethanol (below) and SERS spectrum of 2-mercaptoethanol monolayer formed on roughened silver (above). Spectra are scaled and shifted for clarity. A difference in selection rules is visible: Some bands appear only in the bulk-phase Raman spectrum or only in the SERS spectrum.
