Abstract
The expression for the second - order transformed polarizability operator for non-linear X 2Y - 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 2O 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 2O is analyzed in the calculation of integral intensity of one and two quantum bands.
