Webb1 mars 2009 · By 1925, Raman had observed the frequency-shifted scattered light in more than 50 liquids and, by 1927, he had noticed that the scattered light was polarized. He described the phenomenon—which he called modified scattering—in a paper in Nature. Later it would be called the Raman effect. WebbOur Raman Laboratory for the characterisation of materials. Consulting on Raman spectroscopy applications is also offered. Raman Spectroscopy is the inelastic scattering of photons by phonons. It is a simple, fast, non-destructive characterisation tool widely used in basic and applied research in natural sciences and industries.
WebbRaman understood the need for more intense light sources to amplify the effect and observation of the scattered light. The laser provided an even more intense source of … Webb28 aug. 2024 · Raman spectroscopy is a powerful tool for determining chemical species.

Vibration modes for the same functional groups are observed at the same wavenumber. Though both are forms of vibrational spectroscopy, IR and Raman spectroscopy differ in some fundamental aspects, as shown in Fig. 4 ...
Webb12 juli 2024 · The Raman effect originates from the inelastic scattering of light, and it can directly probe vibration/rotational-vibration states in molecules and materials. Despite numerous advantages over infrared spectroscopy, spontaneous Raman scattering is very weak, and consequently, a variety of enhanced Raman spectroscopic techniques have …
