Since the wobbling of the electrons in a molecule depends strongly on the type of atomic bonds within the molecule, Raman scattering can be used as an extremely sensitive probe of a molecule’s structure. The Raman spectrum of a molecule can even act as its identifying “fingerprint.”

WebThe amplification effect on stimulated Brillouin scattering (SBS) and Rayleigh scattering in the backward pumped G652 fiber Raman amplifier (FRA) is studied. The pump source is a 1427.2-nm fiber Raman laser whose power is tunable between 0-1200 mW, and the signal source is a tunable narrow spectral bandwidth (<10 MHz) external cavity laser … WebWhat is Raman spectrum? Raman scattered light contains various information on molecules in a substance. If you separate the scattered light by wavelength in order to interpret them, you can see that Rayleigh scattered light equal to the wavelength of the incident light is strongly detected and Raman scattered light is detected on both sides as shown in the …
