Refractive indices n_a, n_b and n_c of SbSBr have been found to be 2.64, 3.13 and 4.00, respectively, using modified Chaulnes' method. These values can be explained as being caused by the large electronic polarizabilities of sulfur and bromine. Absorption coefficients for the light having electric vectors parallel to the [100], [110] and [001] were obtained. Although SbSBr is paraelectric in the measured temperature range of -60∼190℃, non-linear temperature dependence of absorption coefficients was observed. The results are discussed in comparison with those for SbSI.
