Abstract content <br> &nbsp; (Max 300 words)

The analysis of Raman and Brillouin scattering spectra requires the knowledge of scattering tensors. Based on Birman's method, we compute the Clebsch-Gordan coefficients for first-order Raman and Brillouin scattering for Bi2Se3 with D3d5 space group symmetry. The linear combination of Clebsch-Gordan coefficients gives the matrix elements of scattering tensors. Our predictions are useful for interpretation of experimental Raman and Brillouin scattering measurements.
