Hello everybody,
I am trying to calculate the irreducible representation of point group 3m (C3v) for NBT (having R3c space group - 161).
Could you please give some clarification in this regard?
Dear Mehdi Babaei
the E bands are degenerate, hence there will be only a single band. So 7A + 6E is correct, summing up to 13 Raman active bands.
See, eg. https://iopscience.iop.org/article/10.1088/0953-8984/12/14/305/pdf
Thank you dear Ladan for your response.
