An analysis of SCF and geometry convergence for diatomic molecules
Cory Christopher Pye · Open Chemistry · 2011
Abstract A geometry and SCF convergence study of Hartree-Fock calculations using the 6-31G* basis set is carried out on the set of all possible diatomic molecules formed from atoms with Z≤36. The utility of Hartree-Fock calculations using the smaller STO-3G basis set to improve the convergence behavior is demonstrated.
