It is shown that the Raman intensity of translational lattice vibrations in β‐Ba(OH) 2 · H 2 O can be explained satisfactorily in terms of bond polarizability parameters obtained from the atom dipole interaction model. The analysis was carried out on the basis of two models. Model A used only bond polarizability parameters for bond stretchings. Model B used bond polarizability parameters for bond stretchings and bond rotations, where the parameters were obtained using only three atomic or ionic polarizabilities. Model B resulted in excellent agreement with observed spectra.
