General Form of the Raman Tensor for Transversely Isotropic Systems

3 General Form of the Raman Tensor for Transversely Isotropic Systems 

In general, the derived polarizability tensor will have a biaxial form, 

This expression is identical in form to equation (5.20). In the case of Raman scattering, however, it is necessary to compute the average Raman tensor, (. For a transversely isotropic system, the segment is free to spin about the r. axis, and the vector ni is averaged over the unit circle normal to r . In addition to (n() = 0 and equation (5.22), we require the result,
