Room- and low-temperature infrared spectra of Copper Chloride Dihydrate(WSDTY) and its deutero modifications have been obtained, as well as polarized spectra of oriented polycrystalline films of the hydrate. Bands due to vibrations of H2O, D2O and HOD molecules in the hydrate, as well as their polarization, are considered in terms of the crystal structure and previous interpretations of the vibrational bands of the solid. Tetrahydropyranyl ethers (THP groups) and 1-ethoxyethyl ethers (EE groups) are removed upon refluxing in 95% EtOH or Me2CO–H2O (95:5) in the presence of a catalytic amount of copper(II) chloride dihydrate (2–5 mol%).
