This effect occurs when an electron enters a virtual excited state, then relaxes by photon emission to a higher or lower vibrational energy level, creating respectively the Stokes and anti-Stokes lines.
Jones and Stoicheff characterized an inverse version of this effect, which relies on the interaction of two different pump waves. In solid-state media, this effect occurs together with the Kerr effect due to the instantaneous response of the electrons, and it is used to induce qubit transitions in ion-trap quantum computing. The selection rule for this process requires a non-zero polarizability derivative, and plasmons are reponsible for its surface-enchanced variety. This effect occurs when an electron enters a virtual excited state, then relaxes by photon emission to a higher or lower vibrational energy level, creating respectively the Stokes and anti-Stokes lines. Also the basis of a type of spectroscopy employing a continuous-wave laser, FTP, name this type of inelastic scattering named for an Indian physicist.
