In this paper, we show that in Raman spectrum of uniaxial crystals, for nonpolar mode and A(z) (or B(z)) mode, under any scattering geometry, x-axis and y-axis are always equivalent. For polar mode E(x) and E(y), in the tetragonal and hexagonal crystal systems, x-axis and y-axis are equivalent in most cases; but in the trigonal crystal system, they are equivalent only in a few cases.
