Learn the fundamentals of Raman spectroscopy and how you can apply this technology to your research, analytical and QA/QC activities. Find basic Raman tutorials, advanced Raman webinars on sample applications, and a helpful instrument guide to build your confidence in Raman spectral analysis.
In Raman spectroscopy, an unknown sample of material is illuminated with monochromatic (single wavelength or single frequency) laser light, which can be absorbed, transmitted, reflected, or scattered by the sample. Light scattered from the sample is due to either elastic collisions of the light with the sample's molecules (Rayleigh scatter) or inelastic collisions (Raman scatter). Whereas Rayleigh scattered light has the same frequency (wavelength) of the incident laser light, Raman scattered light returns from the sample at different frequencies corresponding to the vibrational frequencies of the bonds of the molecules in the sample.
Here you will find video tutorials from our very own Professor, Mike Bradley.
Examine the roots of Raman spectroscopy. Starting with energy levels, we walk through excitation, scattering and interferences.
