Brechzahländerungen durch Schwingungsanregung beim stimulierten Raman-Effekt

The influence of stimulated Raman scattering (SRS) on refractive index due to excitation of vibrational levels of molecules has been estimated for Hydrogen and carbon disulphide. A comparison is given between the changes of refractive index caused by SRS, orientation of molecules and electrostriction. There are shown conditions under which it should be possible to observe such changes and therefore polarizabilities of excited levels.
