In multi‐mode systems with a degenerate excited electronic state, resonance Raman scattering (RRS) can be effectively examined by the Fourier amplitude formalism, where RRS amplitudes are described by the Fourier transforms of phonon correlation functions. Model calculations of REPs of both totally and non‐totally symmetric modes have been carried out in the case of a weak vibronic coupling to off‐diagonal modes. The calculations demonstrate a high sensitivity of RRS to the Jahn–Teller effect for the vibraitons of both the discrete and the continuum spectrum.
