[Pw_forum] 回复： raman tensor of every phonon mode

[肖瑞春]

Thank you for reply！
 But i still don't konw how to use the 'dynmat.x' to get the raman tensor of every phonon mode.  Which parameter should be used?
 and what the relationship of the Raman cross sections and the raman tensor?
 Can you describe in detail? this problem have puzzled me nearly one week!

  Auxiliary code "dynmat.x" computes Raman cross sections for each phonon, for a specific backscattering  geometry.

  Hello everyone!
  I'm studing the tutorial of Raman(example05 in PHonon) , I got the raman tenor of every atom, but we know that the raman intensities are calculated by the raman tensor of every phonon mode. So my qusetion is where is the raman tensor of every phonon mode in the output files ?
