Raman scattering spectra of a KH2PO4 single crystal were measured at various crystal orientations relative to the incident and scattered light propogation directions. It has been found that the contribution of the long-range electrostatic interaction is less than 10 of the total scattering efficiency of the Ex and B2z modes in KDP. A low frequency mode, previously predicted by group theory, was also observed for the first time.
