Local coordinate systems are chosen for each quadruple of atoms relative to a four-center integral, in order to avoid linear combinations of orbitals when symmetry operations perform on an orbital. This choice can utilize the complete molecular symmetry to attain the optimal number of symmetry-uniqu

β¦ Synopsis
A general algebraic theorem IS presented to calculate the matrLz elements of symmetry operators m a bassls of determlnantal wavefunctlons. It IS also shown how the matrix elements of complementary open-shell wavefunctions are related to each other.

In the present article, we outline a simple scheme for generating configuration interaction matrix elements for spinαorbit interactions in molecules. The procedure leads to a close parallelism with spin-free permutation-group approaches. Unitary shift operators were successfully used on the orbital
