Title: RAMAN SCATTERING IN CRYSTALS WITH ORDER-DISORDER TYPE PHASE TRANSITION
Authors: Ya.Ivankiv (Institute for Condensed Matter Physics of the National Academy of Sciences of Ukraine, 1 Svientsitskii Str., 79011 Lviv, Ukraine)

The theory based on the ``operator'' two-time Green functions formalism applied for the construction of the polarizability operators entering the general expression for the effective cross-section of Raman scattering is developed. The presented microscopic scheme is applied to the investigation of the ferroelectrics with hydrogen bonds.
