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. WebOrca has available the Slater Type Orbitals and the Gaussian Type Orbital basis sets, among others, here you can find a list of all basis sets. Convergence on the SCF SCF convergence is a pressing problem in any electronic structure package because the total execution times increases linearly with the number of iterations.
