The dependence of the inverse phase effect on the profiles of absorption lines formed in a Rayleigh-scattering atmosphere is studied for three line profiles in the integrated light of the planet. The atmosphere is assumed to be semiinfinite, plane parallel, isobaric and isothermal, and with a constant ratio of scattering to absorption. The scattering is represented by Rayleigh's phase matrix. Scattering diagrams for the two components and for the total intensity are shown, and the scattering variations for a Lorentz profile are compared with those for a Doppler profile and a Voigt profile. It is found that the inverse phase effect is a function of the line profile chosen, with the Lorentz profile giving the maximum change and the Doppler profile the least.
