Raman spectroscopy is a non-invasive and non-destructive analytical technique, which provides insights into the molecular composition and vibrational modes of matter. This method involves illuminating a sample with monochromatic visible light (with lasers). When light interacts with the molecules in an object, some of the light scatters inelastically, a phenomenon called Raman scattering. Unlike traditional spectroscopy, Raman scattering observes changes in energy levels of scattered photons. These energy shifts are related to the vibrational and rotational motions of molecules within the sample, offering a molecular fingerprint of the substance. These fingerprints need to be compared to a database, to determine the composition and structure of various substances. In Our laboratory a Renishaw InVia Qontor Raman microspectrometer is in operation since 2023.
