Complementarily to the IR spectroscopic technique the Raman spectroscopy informs about bonding relations within the material and about molecule and networking structures. Raman spectroscopy units the spectroscopic advantages within the visible spectral range (high lateral resolution, high sensitivity) with that of the infra-red spectroscopic technique (sensitivity of the structure). The non-contact and non-destructive measuring procedure, in which a laser excites lattice and molecular vibrations, can be applied to very much different materials (ceramics, glasses, plastics, semi-conductors, silicon and carbon.
