Abstract
Vibrational spectroscopy as Infrared (IR) and Raman spectroscopy is used in such various fields as polymer science, semiconductor industry and biochemistry. IR and Raman are useful for characterizing the surface of advanced materials. For example Raman spectroscopy isu tilized for structure determination of the diamond like carbon, which is coated on a magnetic disk. In this report, we discussed principles, systems and applications of IR and Raman spectroscopy. Particularly ATR and RAS (GAR) method are reported as interesting applications of IR spectroscopy.
