Bruker Raman

Raman spectroscopy's principle is the Raman effect, where monochromatic laser light interacts with a sample, causing inelastic scattering where the scattered light has a different energy (frequency and wavelength) than the incident light. This energy difference, or "Raman shift," corresponds to the vibrational and rotational energies of the molecules in the sample. The resulting Raman spectrum provides a "molecular fingerprint" with peaks at specific Raman shifts and intensities that reveal the sample's composition, chemical bonds, and structure.
