Raman spectroscopy is a spectroscopic technique based on the inelastic scattering of monochromatic light generated by a laser. Inelastic scattering means that the frequency of the photons from the monochromatic light changes upon interaction with the sample being analyzed. The photons from the laser light are absorbed by the sample and then emitted. The frequency of the emitted photons is shifted (higher or lower) in relation to the incident monochromatic frequency, which is referred to as the Raman effect. This shift provides information about the vibrational energy changes in the molecules. The obtained Raman spectra provide detailed insights into the molecular and structural composition of a wide range of materials, enabling precise identification and characterization through their unique vibrational signatures.
The laboratory is open for collaboration with academic, innovation, and industrial institutions and firms.
