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.
Go behind the scenes and discover the inner workings of Raman. Three standard Raman events are explained; Rayleigh Scatter, Stokes, and Anti-Stokes.
Understand fluorescence and learn how to avoid it’s interference with the Raman spectrum.
Learn the reasons the Stokes side of the spectrum is most commonly used. You may think it is wise to use the anti-Stoke side of the spectrum to avoid fluorescence, but you never get something for nothing and the price you pay is intensity.
A discussion of why we offer multiple lasers and how FT-Raman helps avoid fluorescence.
Learn how to achieve a virtual state to avoid fluorescence and obtain an accurate Raman scatter. Find the balance in a laser to avoid fluorescence while still gaining efficiency.
Learn how to avoid fluorescence and obtain an efficient Raman scatter.
Examine the fundamentals of Raman – including dipoles versus polarizabilities.
Understand the theoretical basis of what causes a molecule to scatter light. Dive into an explanation using Benzene. Learn more about polarizability - the ability to cause a change within the electron cloud.
Learn how using a polarized laser and analyzer can tell you even more about the molecule.
Learn about the ability of the Raman spectrometer to be sensitive to the polarization of the light and the polarization of the scatter.
