The Raman intensities of cyclohexane and cyclohexane- d12 are interpreted in terms of a modified bond polarizability model. The main emphasis is on the vibrations below 1500 cm -1. Both the spherical and anisotropic parts of the derived polarizability tensors are considered. The observed values of the derived mean polarizabilities were used to evaluate three parameters α' CC, α' HCH, and α' CCC while in a less satisfactory but nonetheless illuminating calculation the derived anisotropies were used to evaluate three more parameters β' CC, β' CH, and β' CC. Uncertainties in the data, the normal coordinate the model are discussed.
