Dear all, I tried to calculation the Ir-Raman cross-section of nanoribbon.
I saw in some topics in the forum that showed that occupations is not used for calculation IR-Raman cross section. However, I can not get the convergence of scf calculation if smearing is not used. Can you give me some instructions to overcome this problem? I appreciate all your helps.
