[Pw_forum] Regarding raman intensity

[Arun Kumar Manna]

Dear All,
        Could anyone please tell me how to get raman intensity values
from raman tensors those are calculated at gamma point?. For 2 atom per unit
cell, I have 6 no. of tensors matrices. I have confusion that in 2 dimension
there should be only 4 optical phonons and corresponding 4 no. of raman
tensor matrices, but i am getting 6 tensors matrices.
     Please help me..
  Thanks,
   Arun
