Webb10 apr. 2024 · Raman scattering occurs when the incident light interacts with a material and causes the molecules in the material to vibrate, resulting in a change in the frequency and phase of the scattered light. This change is known as the Raman shift and is characteristic of the material being penetrated. In optical fibers, Raman scattering can … WebbRaman spectroscopy is based on the Raman effect, which is the scattering of light by molecules, resulting in a shift in the frequency of the scattered light. This frequency shift is proportional to the vibrational energy of the molecule, so by analyzing the scattered light, researchers can learn about the vibrational modes of the molecule and the chemical …
