Comment on 'Selection rules for Brillouin light scattering from eigenvibrations of a sphere' [Chem. Phys. Lett. 461 (2008) 111]

► Selection rules for Brillouin scattering by acoustic vibrations of a sphere. ► Selection rules are based only on the symmetry of the displacements. ► All spheroidal Lamb modes can be Brillouin active for large particles. ► Selection rules for Raman scattering from small particles are also discussed.
