Abstract
The inelastic scattering of light was discovered by Ramanl and, independently, by Landsberg and Madelstam2 after theoretical predictions by Brillouin3 and Smekal. Today, we call Brillouinscattering the scattering of light by long wavelength acoustic phonons (frequency < 10 cm-1) while the term "Raman" is reserved for scattering by optical phonons or by a number of other elementary excitations (magnons, plasmons,electron-hole excitations, polaritons ...) with typical frequencies between 10 and 5000 cm-1.Keywords
