Abstract
Raman spectroscopy is a method to observe the vibration behavior of molecules when they are excited by photons. Since C.V. Raman discovered the Raman scattering effect in 1928, people have gradually paid their attention on this interesting subject. Compare with other analytical techniques, Raman spectroscopy has several distinguishing features.
First, this is an optical methodology thus no destructive damage or invasive behavior will take place. Second, each molecule has its own chemical structure so their vibration modes are highly specific like a chemical fingerprint. Isomers can be distinguished easily even they have identical chemical structure formula and molecular weight. Third, the demands for sample preparation are relative simple. It could be organic or inorganic; solids, liquids or gas. And because the laser spot size is only 1~2
