Abstract
A general formula for the rotational correction of Brillouin scattering tensor is derived based on the coordinate transformation. The exact rotational correction of the scattering tensor related to general acoustic modes and pure modes in the higher symmetry directions, for different crystal systems, is presented. The selfconsistency of the result is explained. The rotational correction in connection with various cases is physically discussed.
