The report describes studies of stimulated Raman scattering SRS and nonlinear index effects in liquids composed of spherically symmetric molecules. It is concluded that although SRS can be observed without self-focusing, nonlinear index effects, presumably because of molecular redistribution, are present and should lead to beam instabilities at somewhat higher powers. Also described are studies of SRS in hydrogen gas pumped by a giant pulse ruby laser. Finally, a theoretical study of the third order polarizability applied to hydrogen, and the resulting coupled Stokes-anti-Stokes waves is described.
