WebMar 7, 2015 · There can be many reasons for the SCF to not converge. The initial guess wasn't great, and the convergence is slow. Increasing the number of SCF iterations can help here. The SCF oscillates. This can happen if there are two orbitals close in energy. WebJan 5, 2024 · The default SCF procedure uses a combination of EDIIS [ Kudin02] and CDIIS, with no damping or Fermi broadening. In Gaussian 16, SCF=Tight is the default. The SCF=QC option is often helpful with difficult conversion cases. For difficult-to-converge ROHF wavefunctions, where QC cannot be used, add Use=L506 to the route section.
