Parametric spectroscopy of Raman scattering of light is proposed and realized. In this method the scattered radiation interacts twice with the scattering-inducing pump and is subjected to parametric transformation with increase of frequency, and is only then detected and analyzed. Among the demonstrated advantages of this procedure are the ease of registration of forward scattering, observation of Raman scattering excited in the IR band in crystals that are opaque to visible light, and others.
