SUMMARY
In 1928, Indian physicists discovered for the first time that there exists an inelastic dispersion, called "Raman scattering", in addition to Rayleigh scattering, after the action of monochromatic light on the molecules of matter. Compared with Rayleigh scattering, Raman scattering is three to six orders of magnitude smaller in intensity, and this scattering is related to the structure of matter, so it can be used for the identification of matter. Since the Raman signal is very weak and requires a strong excitation light source, this has not been widely used for decades after the discovery of the Raman effect. With the rapid development of laser technology, weak signal detection technology, computer applications and instrumentation itself, the application of Raman spectroscopy has gained a breakthrough. This experiment consists of a 785 nm multimode narrow linewidth laser, a microspectrometer, a 785 Raman probe, a sample cell and a holder.
