The Raman spectrum originates from the inelastic scattering of photons by molecules, a phenomenon described by quantum theory. When light interacts with matter, most of the photons are elastically scattered (Rayleigh scattering), retaining their energy. However, a small fraction of photons undergo inelastic scattering, resulting in a shift in their frequency. This shift corresponds to the energy difference between the initial and final vibrational states of the molecule. _____ _________ _______ __________ _____ ____ ____ _______ _______.
