Structural and polarized vibrational studies of pentacaesium trihydrogentetraselenate monohydrate.
Polarized IR and Raman spectra of single crystal were measured at room and at low temperature. The polarized IR spectra were measured by transmission and specular reflection method. The IR-microscope was used for vibrational measurement of small monocrystals. Assignment of the bands is proposed on the basis of oriented gas model approximation. The polarized vibrational spectra are discussed in relation to the crystal structure and possible proton conductivity and phase transition.
