研究了超离子质子导体CsHSO_4（CsDSO_4）在18-450 K范围内的拉曼和红外光谱。还研究了室温下的偏振单晶拉曼光谱和红外反射光谱。由于内部和外部振动的频带分配的对称物种和近似类型的运动。的光谱结果，特别是作为温度的函数的拉曼带的行为，被用来讨论的晶体结构的各个阶段，氢键，类型和程度的结构紊乱，相变和导电性。
The Raman and infrared spectra of the superionic protonic conductor CsHSO4(CsDSO4) were investigated in the 18–450 K range. Polarized single crystal Raman and infrared reflection spectra were also studied at room temperature. An assignment of bands due to internal and external vibrations is given in terms of symmetry species and approximate type of motion. The spectroscopic results, in particular the behaviour of the Raman bands as a function of temperature, are used to discuss the crystalline structures of various phases, hydrogen bonding, the type and degree of structural disorder, phase transitions and conductivity.
