English: Rayleigh and Raman scattering of ethanol observed using a grating and a digital camera (Sony A7 III). The excitation source is a 488 nm argon ion laser. The brightest line is Rayleigh scattering and the lines left side from the Rayleigh line are Stokes Raman scattering. Anti-Stokes Raman lines are also slightly observable at the right side of Rayleigh line.
