Hi All, I have set up a calculation using pw.x -> ph.x -> dynmat.x successfully and plotted myself an IR spectrum. The match to the experimental spectrum is good. However, this is an IR spectrum assuming a powder where the photons are exciting all the modes. I’d now like to calculate the spectrum for a single crystal and specify the electric vector of the photon relative to the crystal. It should preferentially excite certain modes.
Is there a straightforward way to do this using ph.x + dynmat.x? Or perhaps a way to read/print the dipole vectors for each mode so I can dot it with my photon’s e-field? Or another way of thinking about this which is more efficient? (Maybe I missed something in the documentation!)
