The Brookhaven National Laboratory's slow chopper was used to investigate the low frequency motions of hydrogen in KH_2PO_4 and KD_2PO_4 at room temperature and below the ferroelectric Curie temperature. The energy interval covered (8〜170×10^<-3> ev) corresponds to wave numbers of 25〜1300 cm^<-1>, a region which is difficult to be investigated by infrared absorption technique. The excitation modes associated with hydrogen are identified by the change in scattering intensity upon deuteration. It is found that a band of frequencies centered around 180 cm^<-1> is associated with the hydrogen vibrations. A comparison with Reid's semi-empirical theory for KH_2PO_4 is made.
