Raman spectra of crystalline and molten GdCl3

The Raman spectra of crystalline (over a wide temperature range) and molten GdCl3 are mea- sured. The hexagonal structure C26h (UClC26h3 type) of crystalline GdCl3 is found to change weakly over the entire temperature range under study. The temperature dependences of the characteristic frequencies change in the premelting range.
