## Abstract The simulated __ab initio__ molecular orbital (SAMO) method previously applied to RHF closed‐shell and UHF open‐shell situations has been applied to open‐shell radicals, such as the butyl radical and the pentyl radical, within the RHF open‐shell framework. The open‐shell Hartree–Fock th

The crucial role of including d-orbital in predicting geometries of molecuies containing second row atoms in the usual ntom-centred LCAO MO ab initio method is critically discussed. Examples are taken from the lirerature and from calculations on H2S, MeSH and FSN\_employing a variety of basis sets.
