A method of the calculation of optical parameters of the nonisothermal giant planet atmospheres was developed using detailed intensity data of Raman scattering. We have used the model of Morozhenko (A.V. Morozhenko, 1997) as a baseline. In such a way, using observational data of Uranus and Neptune (E.Karkoschka, 1994), the spectral values of ratio of optical depth components: aerosol and gas components \tau a/ \tau R, absorbing and scattering components \tau a/ \tau R, and also single scattering albedo of aerosol component corrected for Raman scattering \omega were obtained (where \tau a, \tau R are aerosol and gas components, and \tau ? is absorbing components of effective optical depths of the formation of diffusely reflected irradiation). The averaged value of ratio \tau a/ \tau R is 0.96 but it slowly decreases in the spectral range of 350-450nm for Uranus and \tau a/ \tau R is 1.35 for Neptune.
