The polarized Raman spectra of Ca (OH)2 and Ca (OD)2 have been obtained using an argon ion laser as an exciting source. All bands predicted by group theory have been observed and their assignments made on the basis of the polarisation data and of the frequency shifts on deuteration. The doubly degenerate translatory and roatory external modes are not completely mixed.
