Abstract The lineshape of the polaritons resulting from the coupled system proton-phonon in KH 2 AsO 4 was calculated for several wavevectors at room temperature. The results are very sensitive to the phase of the coupling, which means that carefull polariton measurements can indicate the correct representation for the coupled system.
