Raman Scattering of K2DxH1-x(SO4)2 Single Crystals Pho Kaung Kasahara, M. Yagi, T. In mixed crystal of K3H(SO.), and K30 (SO.h , the internal modes of HSO. , OSO. and SO were separately observed. In the ordered phase, the splittings between w(HSO.) and w(SO~-), and w(OSO.) and w(SO~-) depend on temperature as (T; - T)~ with 13 = 0.25 ± 0.05. In the disordered state , HSO. and OSO. lines show broaden ing near the transition temperature. Motional narrowing theory developed in nuclear magnetic resonance is app lied to analyse the broaden ing and the correlation time for hydrogen (deu teron) motion is obtained. 1994 http://hdl.handle.net/20.500.12678/0000002589 https://meral.edu.mm/records/2589
