Empirical assignments of the main badns have been made. The solid- solid phase transition at Tp=38℃ in CaCuCL compound has been investigated by the far-infrared spectra with variation of temperatures. It is found that the solid-solid phase transition of this compound waw accompanied by the distortion disorder of the MCL52- octahedra.展开更多
