Raman spectroscopy (Raman) tests the molecular bonding of materials and the structure of samples, which is the basis for detecting material structures. It is highly sensitive in analyzing and determining the characteristic spectral fingerprint region of materials. Raman spectroscopy analysis technology is a molecular structure characterization technology based on the Raman effect, and its signal sources are molecular vibrations and rotations.
