Abstract
Standard sets of Gaussian atomic orbitals (STO‐3G, STO‐4.31G) are used to evaluate spin‐orbit coupling constants in linear molecules (CO, NNN) and spin‐orbit effects on singlet–triplet transition intensities in formaldehyde. All spin‐other orbit effects have been included. In all cases spin‐other orbit interactions form a large fraction of the matrix elements. Simple formulae to evaluate spin‐orbit one‐ and two‐electron integrals over atomic orbitals are presented. Standard molecular integral programs can be used for the computation of spin‐orbit integrals.

A two-component Kramers' restricted Hartree-Fock method (KRHF') has been developed for the polyatomic molecules with closed shell configurations. The present KRHF program utilizes the relativistic effective core potentials with spin-orbit operators at the Hartree-Fock (HF') level and produces molecu
