It occurs because photons colliding with a medium create additional spectral lines, and its observation suggested the existence of photons.
It has great investigative value because the change in energy which it produces is strongly related to the energies needed to move to another rotational or vibrational state. In classical terms, it creates a distortion equal to polarizability times field strength. For liquid compounds, the affected beam has an intensity of only a hundred thousandth of the incident beam. It occurs because photons colliding with a medium create additional spectral lines, and its observation suggested the existence of photons. For ten points, name this effect in which light scattering through a transparent material undergoes a change in frequency.
It has great investigative value because the change in energy which it produces is strongly related to the energies needed to move to another rotational or vibrational state.
