The strong coupling limit of the E⊗ε Jahn-Teller effect is investigated. The high energy part of the JT band shape is shown to exhibit an oscillatory behaviour in this limit. The oscillations are interpreted by adiabatic and Franck-Condon calculations as arising from the vibrational levels of the upper potential energy surface. A new measure of the coupling strength is proposed which is related to the excitation strength of these levels. It is shown to govern the approach of the exact band shape to the semiclassical limit.
