TīmeklisRaman spectroscopy is an analytical technique where scattered light is used to measure the vibrational energy modes of a sample. It is named after the Indian physicist C. V. Raman who, together with his … TīmeklisIn crystals, Raman scattering originates from the vibration of the lattice, which is described in quantum mechanics as phonons. Then we can say Raman scattering in solid is the photons scattered ...
