We have investigated the effects of anharmonicity on the resonance Raman scattering by using the Morse potential for molecular vibration. The Raman intensity is computed by the conventional sum-over-states method. Several conditions in which the anharmonicity effects are manifest have been derived from our numerical calculations. We have also compared our exact results with those of the short time approximation, which is the most tractable approximation in the time-dependent theory of Raman scattering proposed by Heller et al.
