• The temperature dependence of the low-lying pure longitudinal optical phonon mode of B_2(z) symmetry in KDP has been observed by the backward Raman scattering. These B_2(LO) spectra have the under-damped phonon peaks at about 110 cm^<-1>, which are almost temperature independent. This result strongly suggests that the low-lying broad response of y(xy)x Raman spectrum below 〜110 cm^<-1> is primarily the transverse optical phonon excitation.
