Anomaly of the Raman Linewidth of the Internal v2 Mode near the Phase Transition Point of K3D(SO4)2 Pho Kaung Kasahara, Masaru Yagi, Toshirou The linewidth of the internal mode ν 2 of SO 4 2- ion of the antiferroelectric K 3 D(SO 4 ) 2 shows the anomalous broadening with lowering temperature near the phase transition point. The broadening is well explained by a mechanism resembling the motional narrowing phenomenon in the nuclear magnetic resonance theory. The characteristic time of the motion of deuteron in a hydrogen bond is estimated to be on the order of 10 -13 s. 1994 http://hdl.handle.net/20.500.12678/0000002370 https://meral.edu.mm/records/2370
