The resonant coupling of the Γ+5 phonon to the Γ78 CEF excitations in CeAl2 is probed by Raman scattering via the simultaneous observation of the renormalized (Γ̃+6) phonon and the phonon bound state. This represents the “phononic analogue” to the instantaneous observation of electronic charge fluctuations by XPS in intermediate valence compounds.
