Dear quantum esspresso developers,
I have calculated phonon frequencies of the AlSb on the wurtzite structure at the G,K points of hight symmetry, i obtained these frequencies at G 0.00 0.00 0.00 47.02 47.02 151.73 310.79 310.79 316.32 319.33 328.36 335.35and k 81.04 83.45 89.83 90.68 129.95 138.88 294.87 299.38 300.65 302.13 305.12 316.96
My problem is that i dont know how to attribute these frequencies to their corresponding Wurtzite modes (A1(LO),E1(LO), A1(TO),E1(TO), E2h,,,,etc). To be more clear for example the frequency 328.36 corresponds to which mode????????I'll be you so grateful if you help.
regardsNh Ben.
