### Abstract

The expression for the second - order transformed polarizability operator for non-linear X
_{2}Y - type molecules is derived using the method of contact transformation. This operator is used for the calculation of ro-vibrational Raman cross sections of the H
_{2}O molecule. It is shown that the ro-vibrational correction terms change the integral intensity of pure rotational lines significantly and the v
_{2} band slightly. The vibrational dependence of the mean polarizability of H
_{2}O is analyzed in the calculation of integral intensity of one and two quantum bands.
