Stimulated transitions based on this effect are used to manipulate qubits in ion-trap quantum computing, and a French team found that using a polystyrene nanolens can enhance it.  
Stimulated transitions based on this effect are used to manipulate qubits in ion-trap quantum computing, and a French team found that using a polystyrene nanolens can enhance it.  Applying the substrate to a rough gold or silver surface gives a surface-enhanced version of this effect, and it can also be enhanced by plasmon resonance.  It lends its name to a type of spectroscopy employing a continuous-wave laser, which is useful for finding the vibrational and rotational modes of a molecule.  Absorption and emission correspond to the Stokes and anti-Stokes lines, respectively, and it occurs at a much lower incidence than the elastic Rayleigh scattering.  FTP, name this type of inelastic scattering of a photon named for a 1930 Indian Nobel prizewinner.
