Dear all,

I work currently on the phonon dispersions and Raman spectra of some tubular geometries. I particularly need to 

calculate the Raman spectra on two planes in the longitudinal (Z) and transversal polarization (XY) vector configurations.

I have some questions: In the input file of PH.x

1. How to choose a given plane?
2. How to choose the incident and scattered polarization vectors?
3. How to choose a rotation angle in a plan?

Thank you so much before,
